3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sam Ravnborg <sam@xxxxxxxxxxxx>
commit c4619bc6fa5149a6ab39be845a39142b6a996ea5 upstream.
Commit 10b63956 ("UAPI: Plumb the UAPI Kbuilds into the user header
installation and checking") introduced a dependency of make 3.81
due to use of $(or ...)
We do not want to lift the requirement to gmake 3.81 just yet...
Included are a straightforward conversion to $(if ...)
