configure.ac: require pthread-stubs only where available
The project is a thing only for BSD platforms. Or in other words - for
any other platforms building/installing pthread-stubs results only in a
pthread-stub.pc file.
And even where it provides a DSO, there's a fundamental design issue
with it - see the pthread-stubs mailing list for the specifics.
v2: Update comment above the switch statement (Jon Turney).
