Subject: [PATCH] GCC: Pass --plugin to AR and RANLIB
Detect GCC LTO plugin. Pass --plugin to AR and RANLIB to support LTO
build.
* Makefile.tpl (AR): Add @AR_PLUGIN_OPTION@
(RANLIB): Add @RANLIB_PLUGIN_OPTION@.
* configure.ac: Include config/gcc-plugin.m4.
AC_SUBST AR_PLUGIN_OPTION and RANLIB_PLUGIN_OPTION.
* libtool.m4 (_LT_CMD_OLD_ARCHIVE): Pass --plugin to AR and
RANLIB if possible.
* Makefile.in: Regenerated.
* configure: Likewise.
config/
* gcc-plugin.m4 (GCC_PLUGIN_OPTION): New.
libiberty/
* Makefile.in (AR): Add @AR_PLUGIN_OPTION@
(RANLIB): Add @RANLIB_PLUGIN_OPTION@.
(configure_deps): Depend on ../config/gcc-plugin.m4.
* configure.ac: AC_SUBST AR_PLUGIN_OPTION and
RANLIB_PLUGIN_OPTION.
* aclocal.m4: Regenerated.
* configure: Likewise.
zlib/
* configure: Regenerated.
This patch appears to have broken my nios2-linux-gnu target,
x86_64-linux-gnu host cross build:

This is ar version 2.32.51. I also tried with an older set of host
tools using ar 2.25.51 and saw the same failure.
