+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.
