--with-gnu-as does not tell gcc to *look* for GNU as, it just tells it
to assume the assembler it will find is GNU as.  As stated in the FAQ,
gcc -print-search-dirs tells which directories it searches, and only
if it does not find an assembler in any of those directories will it
search the PATH.  So you have to create links before you start
building, or create them in the build directories too, as explained
in the patch below.
