Correctly define mcontext for HPPA

libc-alpha,

A machine context is really a signal context.

This has never worked correctly in hppa since the kernel has always returned a sigcontext instead of the struct defined in ucontext.h.

This definition change is made such that glibc matches the ABI, rather than presenting an odd view of mcontext_t.

The only thought I have...

- Is there enough information in our sigcontext to implement [set,get,make,swap]context calls?

c.

* sysdeps/unix/sysv/linux/hppa/sys/ucontext.h:
Define mcontext_t as a sigcontext.
