I agree that I'd prefer we detect whether the target-specific clamped version is to blame (and use the proposed warning message) or the original DWARF version is to blame (and use the old message). If I were compiling for x86 and gave e.g. `-gdwarf-4 -gembed-source` and the error said "not supported by target" I'd probably get the wrong idea. It would also be nice to retain the error semantics in the case where the user is explicitly requesting incompatible options.
