[PATCH 13/16] ld/Makefile.am: Introduce a libld.la

[David Malcolm <dmalcolm@redhat.com>]

Similarly to "libgas.la" before , this introduces a libld.la, moving
everything from "ld" into it, with ld built from ldmainmain.c.

As before with the libgas.la patch, this patch isn't ready yet, but
seems to be good enough for prototyping the libgccjit.so integration.
