Subject: [PATCH/take 2] ppc: fix build with O=$(output_dir)
OK, here's a patch that builds a separate copy for arch/ppc/boot/lib.
Recent changes to arch/ppc/boot/lib/Makefile cause
CC arch/ppc/boot/lib/../../../../lib/zlib_inflate/infblock.o
Assembler messages:
FATAL: can't create arch/ppc/boot/lib/../../../../lib/zlib_inflate/infblock.o: No such file or directory
when building a ppc kernel using O=$(output_dir) with CONFIG_ZLIB_INFLATE=n,
because the $(output_dir)/lib/zlib_inflate directory doesn't get created.
This patch, which uses the lib/zlib_inflate sources to build objects
in the arch/ppc/boot/lib/directory, is one fix for the problem.
