[parisc-linux] [PATCH] 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.
