Subject: [PATCH 1/3] Fix parallel make failure for archives

Upstream-Status: Pending

The lib and gnuefi makefiles were using the lib.a() form which compiles
and ar's as a pair instead of compiling all and then ar'ing which can
parallelize better. This was resulting in build failures on larger values
of -j.

See http://www.chemie.fu-berlin.de/chemnet/use/info/make/make_toc.html#TOC105
for details.
