testsuite/newlib.locale/UTF-8.exp: Don't run if multibyte support is
disabled.

Regression testing newlib in conjunction with libgloss and
--enable-multilib can result in incompatible multilib versions of
newlib and libgloss being used during link.
This manifests on ARM target when newlib regression is run using a
GCC configured using --with-multilib-list=aprofile
With this configuration many of the multilib variants built are
mutually incompatible.
The issue is that the newlib dejagnu foo iterates each multilib
variant and correctly chooses the appropriate newlib variant but
always chooses the root/base libgloss variant.
The implementation of newlib/testsuite/lib/flags.exp contains the
following fragment:
set target_build_path "$objdir/$multibuildtop.."
The effect of this fragment is to explicitly select the root version
of libgloss, irrespective of the current multilib.
Digging around in VC it appears that the original implementation of
multlib magic came into the tree back in 2002 with:
6e9d950a (Thomas Fitzsimmons 2002-05-01 17:06:25 +0000 39)
In this initial version of multilib support, newlib was multilib
capable, but libgloss was not multilib capable, hence the necessity to
explicitly select the root libgloss version.
Subsequently flags.exp was modified to support out of tree testing:
cec1d3b4 (Jeff Johnston 2005-07-05 00:11:50 +0000 25)
This change is orthogonal to this issue, its effect is to exit early
in none multilib configurations.
Subsequently libgloss gained --enable-multilib support, the relevant
change is:

This change enabled multilib support throughout libgloss, but ommitted
to adjust the flag.exp behaviour which anchors the libgloss multilib
selection to the base version.
The attached patch adjusts flags.exp to select the current multilib
variant of libgloss.

* testsuite/lib/flags.exp (libgloss_link_flags): Drop multilibtop
from target_build_path.
* testsuite/newlib.stdio/swprintf.c (main): Change size of value
used to initialise 'val' variable so that it will compile on
targets with 32-bit doubles.
* libc/stdio/vfwprintf.c (wcvt): Add a new parameter len of type
int. *length is set to the value of (rev - digits) regardless
of whether _MB_CAPABLE is defined or not. Replace BUF with len
in calling _mbsnrtowcs_r and also in the loop where _MB_CAPABLE
is not defined.
(_VFWPRINTF_R): Call wcvt with an extra argument. Call wcvt
again with allocated new buffer if buf is not large enough for
the conversion.
* testsuite/newlib.stdio/stdio.exp: New.
* testsuite/newlib.stdio/swprintf.c: Likewise.
* testsuite/lib/checkoutput.exp (newlib_check_output): Use test
names after PASS and FAIL which do not depend on source directory
name or on whether test passed or failed.
* testsuite/lib/passfail.exp (newlib_pass_fail): Likewise.
* Makefile.am (site.exp): Set tmpdir.
* Makefile.in: Regenerated.
* testsuite/lib/checkoutput.exp (newlib_check_output): Put
executables in $tmpdir.

libgloss version if not running in the build directory.
* testsuite/lib/newlib.exp (newlib_init): Put testglue.o in
$tmpdir.
* testsuite/lib/passfail.exp (newlib_pass_fail): Put executables
in $tmpdir.
* configure.host: Remove -DLOOSE_KERNEL_NAMES flag for linux
x86 build.
* iconvdata/Makefile.am: Make dependent on newlib's configure.host
and set up default flags to pass to aclocal.
* iconvdata/Makefile.in: Regenerated.
* libc/sys/linux/Makefile.am: Add _ELIX_LEVEL_4 getlogin, getpwnam,
and getpwuid routines.
* libc/sys/linux/Makefile.in: Regenerated.
* libc/sys/linux/getlogin.c: New stub file to allow x86-linux
applications to link with newlib's shared libc library.
* libc/sys/linux/getpwnam.c: Ditto.
* libc/sys/linux/getpwuid.c: Ditto.
* libc/sys/linux/sys/types.h: Include <features.h> and supply types
that were formerly supplied by /usr/include/linux/types.h with
kernel types.
* testsuite/newlib.wctype/twctype.c: Fix testcase to properly
test _ELIX_LEVEL macro.
* testsuite/lib/passfail.exp (newlib_pass_fail): Changed to
only issue one pass/fail message for a compile/link/execute.
* testsuite/newlib.elix/elix.exp: New file.
* testsuite/newlib.elix/tmmap.c: Ditto.
* testsuite/include/check.h: New header file to use with
test cases.

to list of header files to use.

to something more reasonable for embedded platforms.
only one pass or fail per test file. Trim \r's from output
values received from test programs. Remove support for named
tests.
* testsuite/newlib.locale/UTF-8.exp: Update to support new
newlib_check_output behaviour.
* testsuite/newlib.locale/UTF-8.c: Likewise.
