Skimming through the LLVM it's not obvious what is the before/after
output of `llvm-config --version'. Can anyone share some examples?

It sounds like one decided to omit the "svn" (or equivalent) from the
string returned, while the DSO still has it.

Speaking of breakage - 3.9.1 has broken llvm-config
--libnames/libfiles [1] ... sigh.
If there's a for 3.9.2 we might want to nominate it ;-)
