From: "H.J. Lu" <hjl.to...@gmail.com>
AR from older binutils doesn't work with --plugin and rc:
[hjl@gnu-cfl-2 bin]$ touch foo.c
[hjl@gnu-cfl-2 bin]$ ar --plugin
/usr/libexec/gcc/x86_64-redhat-linux/10/liblto_plugin.so rc libfoo.a foo.c
[hjl@gnu-cfl-2 bin]$ ./ar --plugin
/usr/libexec/gcc/x86_64-redhat-linux/10/liblto_plugin.so rc libfoo.a foo.c
./ar: no operation specified
[hjl@gnu-cfl-2 bin]$ ./ar --version

Check if AR works with --plugin and rc before passing --plugin to AR and
RANLIB.

* configure: Regenerated.
* libtool.m4 (_LT_CMD_OLD_ARCHIVE): Check if AR works with
--plugin and rc before enabling --plugin.
