Subject: 	* config/unix-ld.exp: Set ld using findfile.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5c680d3f29a0f7073b32e00bc5d4fda17c5e89f0;p=binutils-gdb.git

	* config/unix-ld.exp: Set ld using findfile.
	* lib/ld.exp (default_ld_relocate): Return a value.  Change format
	of log messages.
	(default_ld_compile): Likewise.
	(default_ld_link): Likewise.  Also, don't include $BFDLIB and
	$LIBIBERTY in link.
	* ld.bootstrap/bootstrap.exp: Rewrite.
	* ld.cdtest/cdtest.exp: Rewrite.
	* ld.cdtest/cdtest-foo.cc: Update from top level ld directory.
	* ld.cdtest/cdtest-foo.h: Likewise.
	* ld.cdtest/cdtest-main.cc: Likewise.
