Subject: This patch prevents a linker testsuite error if the checks are run with a
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=19aef622f37ae4f940d6e3ef6835fd5519289178;p=binutils-gdb.git

toolchain that just contains the binutils - ie without a compiler.

	* lib/ld-lib.exp (check_lto_available): Check that a compiler is
	available before testing for LTO support.
