<sys/ucontext.h> on alpha

<sys/ucontext.h> on alpha

[Andreas Jaeger]

Trying to compile the current glibc 2.2 on alpha, I noticed that
<sys/ucontext.h> isn't in synch with the other architectures.
Appended is a patch to add the missing parts.  I'd appreciate if
somebody would check if this is ok.

	other architectures: Add NGREGS, greg_t, gregset_t, _fpstate.

I've checked in a little bit different patch which is in sync with the
definitions in asm/elf.h.
