[PATCH] binuitils: Check if AR is usable for LTO build

[H.J. Lu]

Check if AR is usable for LTO build with --enable-pgo-build=lto:

checking for -plugin option... ar: no operation specified
Failed: ar --plugin /usr/gcc-11.0.0-x32/libexec/gcc/x86_64-pc-linux-gnu/11.0.0/liblto_plugin.so rc
no
configure: error: AR with --plugin and rc is required for LTO build

instead of build failure later.

	PR binutils/26766
	* configure.ac:
	* configure: Regenerated.
