gcc knows how to link threaded applications on all the platforms on which
it supports threading, and if you just give it -pthread, it figures it
out.  Sometimes this involves linking with libc_r instead, sometimes it
means linking with libc_r first, sometimes it doesn't change what C
library it uses at all.  But the point is more that listing -lc on the
link line is almost certain to mess something up, since gcc is smarter
than Python's configuration scripts.
