[9fans] getcontext/setcontext for ARM on linux

[Ronald G Minnich]

if anybody has the source of these lying around handy, I could use 'em. 
I can attempt to write them but I'd rather use known-good stuff than 
stumble around in the dark. I have got p9p running save for libthread at 
this point on the ts7200 lunchbox on linux.

When in doubt, start with someone else's setjmp/longjmp
for that platform.  I would use those directly except that I don't
want to fiddle with the signal mask and they usually do.

good enough, that is kind of what I am doing.

I was surprised at lack of context stuff in latest glibc, but I guess it 
is not that much used on arm.
