[oe] [2011.03-maintenance 1/5] llvm2.7_2.7: Add patch for build errors on newer gcc / glibc combinations

[Steffen Sledz]

From: Stefan Schmidt <stefan at buglabs.net>

Its seems there is a stricter header checking again which results in errors like
this:
error: 'ptrdiff_t' does not name a type

This happens on my Debian SID system. Adding the needed includes fixes the
build.
