The way I read it, --with-gnu-ld means that libtool should look for
GNU ld (in $PATH, skipping past any other ld that doesn't pass
muster), it is not meant to force libtool into using some random ld
as if it was GNU ld.

So, it appears that LT_PATH_LD does not like your ld? I'd look into
that. Btw, is $GCC "yes"?
