Why run it only on linux?  It might pass perfectly well on other
systems -- and if not, it's a bug there too, which we might want
to know.

Definitely.  I thought the link process (-lpthread) was linux-only.
Can we write portable code in the test suite that builds
multi-threaded programs?

We already have -- see pthread.exp

Here's a revision of the patch, which uses the gdb_compile_pthreads
function introduced by the last patch I posted ("RFA: abstract out
thread compilation code").  It no longer refuses to run on anything
but Linux.
