newlib: Remove automake option 'cygnus' 
The 'cygnus' option was removed from automake 1.13 in 2012, so the
presence of this option prevents that or a later version of automake
being used.

A check-list of the effects of '--cygnus' from the automake 1.12
documentation, and steps taken (where possible) to preserve those
effects (See also this thread [1] for discussion on that):

[1] https://lists.gnu.org/archive/html/bug-automake/2012-03/msg00048.html

1. The foreign strictness is implied.

Already present in AM_INIT_AUTOMAKE in newlib/acinclude.m4

2. The options no-installinfo, no-dependencies and no-dist are implied.

Already present in AM_INIT_AUTOMAKE in newlib/acinclude.m4

Future work: Remove no-dependencies and any explicit header dependencies,
and use automatic dependency tracking instead.  Are there explicit rules
which are now redundant to removing no-installinfo and no-dist?

3. The macro AM_MAINTAINER_MODE is required.

Already present in newlib/acinclude.m4

Note that maintainer-mode is still disabled by default.

4. Info files are always created in the build directory, and not in the
source directory.

This appears to be an error in the automake documentation describing
'--cygnus' [2]. newlib's info files are generated in the source
directory, and no special steps are needed to keep doing that.

[2] https://lists.gnu.org/archive/html/bug-automake/2012-04/msg00028.html

5. texinfo.tex is not required if a Texinfo source file is specified.
(The assumption is that the file will be supplied, but in a place that
automake cannot find.)

This effect is overriden by an explicit setting of the TEXINFO_TEX
variable (the directory part of which is fed into texi2X via the
TEXINPUTS environment variable).

6. Certain tools will be searched for in the build tree as well as in the
user's PATH. These tools are runtest, expect, makeinfo and texi2dvi.

For obscure automake reasons, this effect of '--cygnus' is not active
for makeinfo in newlib's configury.

However, there appears to be top-level configury which selects in-tree
runtest, expect and makeinfo, if present. So, if that works as it
appears, this effect is preserved. If not, this may cause problem if
anyone is building those tools in-tree.

This effect is not preserved for texi2dvi. This may cause problems if
anyone is building texinfo in-tree.

If needed, explicit checks for those tools looking in places relative to
$(top_srcdir)/../ as well as in PATH could be added.

7. The check target doesn't depend on all.

This effect is not preseved. The check target now depends on the all
target.

This concern seems somewhat academic given the current state of the
testsuite.

Also note that this doesn't touch libgloss.

1f8e5847df libm: Fix 'gamma' and 'gammaf' functions. Clean up other gamma code. [v2] 
The current gamma, gamma_r, gammaf and gammaf_r functions return
|gamma(x)| instead of ln(|gamma(x)|) due to a change made back in 2002
to the __ieee754_gamma_r implementation. This patch fixes that, making
all of these functions map too their lgamma equivalents.

To fix the underlying bug, the __ieee754_gamma functions have been
changed to return gamma(x), removing the _r variants as those are no
longer necessary. Their names have been changed to __ieee754_tgamma to
avoid potential confusion from users.

Now that the __ieee754_tgamma functions return the correctly signed
value, the tgamma functions have been modified to use them.

libm.a now exposes the following gamma functions:

    ln(|gamma(x)|):

	__ieee754_lgamma_r
	__ieee754_lgammaf_r

	lgamma
	lgamma_r
	gamma
	gamma_r

	lgammaf
	lgammaf_r
	gammaf
	gammaf_r

	lgammal	(on machines where long double is double)

    gamma(x):

	__ieee754_tgamma
	__ieee754_tgammaf
	tgamma
	tgammaf
	tgammal (on machines where long double is double)

Additional aliases for any of the above functions can be added if
necessary; in particular, I'm not sure if we need to include
__ieee754_gamma*_r functions (which would return ln(|(gamma(x)|).

c156098271 New expf, exp2f, logf, log2f and powf implementations 
Based on code from https://github.com/ARM-software/optimized-routines/

This patch adds a highly optimized generic implementation of expf,
exp2f, logf, log2f and powf.  The new functions are not only
faster (6x for powf!), but are also smaller and more accurate.
In order to achieve this, the algorithm uses double precision
arithmetic for accuracy, avoids divisions and uses small table
lookups to minimize the polynomials.  Special cases are handled
inline to avoid the unnecessary overhead of wrapper functions and
set errno to POSIX requirements.

The new functions are added under newlib/libm/common, but the old
implementations are kept (in newlib/libm/math) for non-IEEE or
pre-C99 systems.  Targets can enable the new math code by defining
__OBSOLETE_MATH_DEFAULT to 0 in newlib/libc/include/machine/ieeefp.h,
users can override the default by defining __OBSOLETE_MATH.
Currently the new code is enabled for AArch64 and AArch32 with VFP.
Targets with a single precision FPU may still prefer the old
implementation.

libm.a size changes:
arm: -1692
arm/thumb/v7-a/nofp: -878
arm/thumb/v7-a+fp/hard: -864
arm/thumb/v7-a+fp/softfp: -908
