Setting LD tool default to ld breaks configure check for ld used by GCC

The above line comes from libtool.m4.  If we set LD="" in the toplevel
configure script, the libtool script then sets LD to ld program used by
GCC.  However, this define for LD isn't a proper default.  So, I am
wondering if the libtool script should also reset LD when LD=ld?
