There is an issue with llvm-config without version when multiple
versions of llvm are built:

WARNING: The recipe llvm2.8 is trying to install files into a shared
area when those files already exist. Those files and their manifest
location are:
   /home/jenkins/oe/shr-core-branches/shr-core/tmp-eglibc/sysroots/qemuarm/usr/bin/crossscripts/llvm-config
   Matched in manifest-qemuarm-llvm3.2
manifest-qemuarm-llvm2.9
manifest-qemuarm-llvm-common
Please verify which package should provide the above files.

Shouldn't we stage llvm-common only once and only from llvm-common
recipe? Not caused by this change, but
http://patchwork.openembedded.org/patch/50959/

Other recipes can stage llvm-commonVER.
