[PATCH] glibc 2.2.94 - hppa - pthreads support

[Carlos O'Donell <carlos at baldric dot uwo dot ca>]

libc-alpha,

Adding pthreads support to hppa.  

Modified patch: removed files related to IPC on hppa, and updated
for PowerPC 32/64 pt-machine.h split to match latest 2.2.94 changes.  

Cheers,
c.
