mesa.inc: drop wrong path in --with-llvm-prefix and export LLVM_CONFIG
* this was added in oe-core/pyro but breaks all builds with llvm from
meta-oe as reported in:
http://lists.openembedded.org/pipermail/openembedded-core/2017-April/135050.html
* fix it by partial backport from master:
http://git.openembedded.org/openembedded-core/commit/?id=
da29bc17e4dd748f50b054c5e3afaf8d41bf4077
but with different path as llvm-3.3 from meta-oe installs llvm-config in:
${STAGING_BINDIR_CROSS}/llvm-config
while llvm-5.0 from oe-core master (rocko) in:
${STAGING_LIBDIR}/llvm${MESA_LLVM_RELEASE}/llvm-config-host"
