Subject: [PATCH] build-llvm: Simplify handling of the --pgo=<file> option

These variable expansions/modifications work the same if the
option "--pgo" is specified - so either we can simplify the
stripping of the "--pgo=" prefix, or we can just skip the check,
similar to the case above with --instrumented.
