The glib commit message indicates it is intentional change, in order
to get POSIX compliance:

  https://sourceware.org/git/?p=glibc.git;a=commit;h=251287734e89a52da3db682a8241eb6bccc050c9

NB, other parts of QEMU like the coroutine code are already
using the 'ucontext_t' typedef, so attaining consistency across
files is good regardless of the glibc change.

Regards,
Daniel
