[Bug bootstrap/25672] cross build's libgcc picks up CFLAGS

["pluto at agmk dot net" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #2 from pluto at agmk dot net  2006-01-05 02:45 -------
moreover the buildsystem doesn't propagate -I$target-headers-directory
specified in configure by --with-headers=$dir and build fails.

below log comes from powerpc (host, build: ppc32, target: ppc64):
