Subject: Check $READELF_FOR_TARGET for readelf in configure
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=32a18c8c93123416beecaca56d7edf4ba00ddb79;p=gcc.git

Check $READELF_FOR_TARGET for readelf in configure

Similar to as, ld, nm and objdump, gcc configure should check
$READELF_FOR_TARGET for readelf.

	PR bootstrap/67385
	* configure.ac (gcc_cv_readelf): Check $READELF_FOR_TARGET.
	* configure: Regenerated.
