Add CLANG_PLUGIN_FILE to find the clang plugin file and pass it to
--plugin for ar, nm and ranlib so that binutils can be built with
clang LTO. Run CLANG_PLUGIN_FILE before GCC_PLUGIN_OPTION since
GCC_PLUGIN_OPTION may return the wrong PLUGIN_OPTION with clang.

libiberty: Use x86 HW optimized sha1
broke Solaris/x86 bootstrap with the native as:
libtool: compile: /var/gcc/regression/master/11.4-gcc/build/./gcc/gccgo -B/var/gcc/regression/master/11.4-gcc/build/./gcc/ -B/vol/gcc/i386-pc-solaris2.11/bin/ -B/vol/gcc/i386-pc-solaris2.11/lib/ -isystem /vol/gcc/i386-pc-solaris2.11/include -isystem /vol/gcc/i386-pc-solaris2.11/sys-include -fchecking=1 -minline-all-stringops -O2 -g -I . -c -fgo-pkgpath=internal/goarch /vol/gcc/src/hg/master/local/libgo/go/internal/goarch/goarch.go zgoarch.go

As is already done in a couple of other similar cases, this patches
disables hwcaps support for libiberty.
Initially, this didn't work because config/hwcaps.m4 uses target_os, but
didn't ensure it is defined.
Tested on i386-pc-solaris2.11 with as and gas.

This commit has not yet been applied to the master sources in the gcc repository.
It was submitted here: https://gcc.gnu.org/pipermail/gcc-patches/2021-July/574405.html
The commit allows options to be set for the AR and RANLIB programs used when building libiberty, which in turn allows building with LTO enabled.
(libiberty_AC_FUNC_STRNCMP): Use AC_LIBOBJ.
(LIB_AC_PROG_CC): Remove.
* configure.in: Update AC_PREREQ to 2.57. Use GCC_NO_EXECUTABLES.
Use AC_PROG_CC and set ac_libiberty_warn_cflags instead of using
LIB_AC_PROG_CC. Use AC_LIBOBJ. Call AC_ISC_POSIX later, only if
performing link tests.
* configure: Regenerated.
(AC_DEFINE_NOAUTOHEADER): New - work around bug in autoheader.
* configure.in: Call AC_C_INLINE and AC_C_CONST. Use three
argument form of AC_DEFINE in dummy definitions block. Use
AC_DEFINE_NOAUTOHEADER for real definitions of things defined
in dummy block. Preload cache variables instead of bypassing
tests, where possible.
* acconfig.h: Removed.
* xmalloc.c (xmalloc_failed): New function, does error
reporting on failed allocation.
(xmalloc, xcalloc, xrealloc): Use it.
