From: Khem Raj <raj.khem at gmail.com>

This patch makes sure that we always use the GNU ld. u-boot uses certain
construct e.g. OVERLAY which are not implemented in gold therefore it
always needs GNU ld for linking. It works well if default linker in
toolchain is GNU ld but in some cases we can have gold to be the
default linker and also ship GNU ld but not as default in such cases
its called $(PREFIX)ld.bfd, with this patch we make sure that if
$(PREFIX)ld.bfd exists than we use that for our ld. This way it
does not matter what the default ld is.
