binutils/binutils: add blind option to force use of ld.bfd during build

Browse Source 
gold is not capable of building glibc/eglibc, so we have to
force using the BFD linker, ld.bfd.

Offer a blind option that affected components can select to
force use of the BFD linker during the build.

Both the historical ld and the new gold linkers will be
