Florian Weimer 2c41b52901 debug/tst-longjmp_chk2: Make signal handler more conservative [BZ #20248]
Currently, printf needs more stack space than what is available with
SIGSTKSZ.  This commit use the the write system call directly instead.

Also use sig_atomic_t for the “pass” variable (for general
correctness), and restore signal handlers to their defaults, to avoid
masking crashes.

Mike Frysinger 5896c8bdd9 tst-longjmp_chk2: add comments/sanity check
If the longjmp checking code is slightly broken, this code can loop
forever which isn't too helpful.  Add a sanity check to keep that
from happening.
