Re: Libc support for old BSD-style "sigcontext" signal handlers is broken, let's just kill it.

I think the point is that the "old dynamic libc" is the current libc,
unless an old binary is so old that it linked against libc.11 or earlier
(which means way back into the last millenium sometime).

So not only is kernel support needed, libc (12) support is as well.  Once
the fabled libc version bump happens this will all change.
