Update mit-pthreads for 1.3H signal changes on alpha and i386. Update mit-pthreads for 1.3/1.3H on sparc (from 1.1 version). Enable building the server on sparc. Add mit-pthreads support for 1.3/1.3H on arm32. (Server doesn't work yet.) Fix two bugs in mit-pthreads with functions returning off_t's.
