Use the more official fesetenv(FE_DFL_ENV) from _dll_crt0, thus
allowing to drop the _feinitialise declaration from fenv.h.
Provide a no-op _feinitialise in Cygwin as exportable symbol for really
old applications when _feinitialise was called from mainCRTStartup in
crt0.o.

Drop the Cygwin-specific fenv.cc and fenv.h file and use the equivalent
newlib functionality now, so we have at least one example of a user for
this new mechanism.
fenv.c: allow _feinitialise to be called from Cygwin startup code
fenv.h: add declarations for fegetprec and fesetprec for Cygwin only.
Fix a comment.

This Patch removes Soft Float code from MIPS.
Instead It adds the soft float code from RISCV
The code came from FreeBSD and assumes the FreeBSD softfp
implementation not the one with GCC. That was an overlooked and
fixed in the other fenv code already.

For RISC-V targets without hardware FMA support, include the
common fma implementation to provide that API.

Like ARM, some RISC-V implementations have hardware sqrt. Support for
that can be detected at compile time, which the code did. However, the
filenames were incorrect so that both the risc-v specific and general
code were getting included in the resulting library.
Fix this by following the ARM model and #include'ing the general code
when the architecture-specific support is not available.

This is required to avoid colliding with files built from libm/common
that would end up with the same object name.
When libm.a was constructed from the individual sub-libraries, the
contents of the libm/common files would be replaced by that from
libm/machine/arm with the same name.

When HAVE_FAST_FMAF is set, use the vfma.f32 instruction, when
HAVE_FAST_FMA is set, use the vfma.f64 instruction.
Usually the compiler built-ins will already have inlined these
instructions, but provide these symbols for cases where that doesn't
work instead of falling back to the (inaccurate) common code versions.

Use the already existing stub files if possible. These files are
necessary to override the stub implementation with the machine-specific
implementation through the build system.

The previous fenv support for ARM used the soft-float implementation of
FreeBSD. Newlib uses the one from libgcc by default. They are not
compatible. Having an GCC incompatible soft-float fenv support in
Newlib makes no sense. A long-term solution could be to provide a
libgcc compatible soft-float support. This likely requires changes in
the GCC configuration. For now, provide a stub implementation for
soft-float multilibs similar to RISC-V.
Move implementation to one file and delete now unused files. Hide
implementation details. Remove function parameter names from header
file to avoid name conflicts.
Provide VFP support if __SOFTFP__ is not defined like glibc.

Having symlinks for these files led to an issue reported to the RTEMS
Project that showed up using some tar for native Windows to unpack the
newlib sources. It creates symlinks in the tar file as copies of the
files the symlinks point to. If the links appear in the tar file before
the source exists, it cannot copy the file.
The solution in this patch is to convert the files that are symbolic
links into simple files which include the file they were linked to.
This should be more portable and avoids the symbolinc link problem.
The TI proprietary toolchain uses nonstandard names for some math
library functions. In order to achieve ABI compatibility between
GNU and TI toolchains, add support for the TI function names.
