Subject: [net] wireless: fix build when using O=objdir
Message-id: <20091215171051.GH22227@redhat.com>
Patchwork-id: 21967
O-Subject: Re: [RHEL5.5 urgent PATCH] wireless: use internal regulatory database
	infrastructure
Bugzilla: 546712

For some reason using make O=<objdir> fails to build because it can't find
the above awk script.  Building a second time seems to work.  Proably
just a silly Makefile bug using objdirs.

Jeff B. wrote a buildcheck test in rhts that tries to mimic how a
developer might compile a kernel, because we have been burned in the past
where it compiled on beehive/brew but locally it failed.  Anyway he stuck the
O=<objdir> option in there and that is where we see the problem.

So running

make -jX O=<objdir>
make -jX O=<objdir> modules

should mimic the problem.

Here's the fix:
