Subject: [3.7-rc6] Build failure with scripts/Makefile.headersinst

I get build error which complains that include/uapi/asm-generic/auxvec.h is
missing although the file exists. I'm using gcc 3.3.5.
This bug seems to not happen with gcc 4.x.

Linux 3.6 builds fine. I can't use "git bisect" until Linux 3.7-rc6 but
possibly caused by either commit 10b63956 "UAPI: Plumb the UAPI Kbuilds into
the user header installation and checking" or commit 40f1d4c2 "UAPI: Remove the
objhdr-y export list".
