Subject: [PATCH] binutils runtest $CC

I noticed in the binutile Makefile that runtest is being invoked with
CC, CC_FOR_BUILD and other compiler related flags in the environment.
That doesn't work.  Those variables ought to be passed on the runtest
command line.

After fixing that I had some fails due to binutils testprog.c now
being compiled with the default "-g -O2" picked up in
CFLAGS_FOR_TARGET.  Hack around that by passing -O0.

Also, with the binutils testsuite now taking notice of CC_FOR_TARGET,
I found a couple of debuginfod.exp fails with one of my compilers that
happened to be built without --debug-id being enabled by default.

	* Makefile.am (check-DEJAGNU): Pass $CC and other variable on
	the runtest command line rather than futilely in the
	environment.  Add -O0 to CFLAGS_FOR_TARGET.
	* Makefile.in: Regenerate.
	* testsuite/binutils-all/debuginfod.exp: Compile testprog.c
	with -Wl,--build-id.
