[GIT PULL] tile bug fix for v3.10

From: Chris Metcalf

Please pull the following change for 3.10 from:

git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile.git stable

This change allows the older tilepro architecture to be correctly
built by newer gccs, despite a change that caused gcc to start
trying to use an out-of-line implementation for __builtin_ffsll().
This should be inline again starting with gcc 4.7.4 and 4.8.2 or so,
but meanwhile this change keeps things from breaking, with the only
cost being a few bytes of code in the kernel to provide __ffsdi2
even for compilers that do inline it.
