The following patch takes TUNE_PKGARCH into consideration instead
of TARGET_ARCH and results in signatures as expected.

reluctanly, this is ok for now. But I think we need to think this fresh
and limit the tune specific changes a bit better, llvm takes a long time
to compile and this could be inefficient for fleet of similar looking SOCs
