Hmm, fired that off a bit quick.  The code that sets gcc_cv_nm and
gcc_cv_objdump should also lose the build != host test, I think.
Also, when running configure to generate auto-build.h, we should be
using target_alias and build_alias.  Otherwise, I find it looking
for tools like powerpc64-unknown-linux-gnu-as instead of
powerpc64-linux-as.

	* configure.in (auto-build.h): Use target_alias and build_alias
	when running configure.
	(gcc_cv_as, gcc_cv_ld): Search install paths when build != host too.
	(gcc_cv_nm, gcc_cv_objdump): Set for build != host too.
	* configure: Regenerate.
