Not sure if that's a LLVM versioning issue. On our side, we could change the line to this but also not sure if that's more a hack.

`cd "$DESTDIR$TARGETDIR/lib/clang/*/lib" || exit 1`

This makes cd using whatever is there. Since the XGCC folder is always specific to one toolchain version, thus it shouldn't contain multiple versions of Clang, there should always be just one folder.

Opinions?
