That is in an interesting idea.  I like it.

Me too.

It doesn't help with Bruno's use case, detecting the integrated
libpthread with the preprocessor.

It might be good enough for that use case, if the detection of LIBPTHREAD_SO==LIBC_SO can be done at 'configure' time instead of at preprocessor time. (Bruno would be a better person to opine on this.)
