u-boot_2011.09, u-boot_2011.12: Always use gnu ld for LD

u-boot wants GNU ld and cant link with gold
so when default linker is gold we make sure
that it still uses good old GNU ld

+Subject: [PATCH] config: Always use GNU ld
+
+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.
+
+Upstream-status: Pending
