Good catch, I didn't notice the 'if' is kind of an optimization for the
scenarios where <arch>_get_longjmp_target is not provided. Moving it
down before that 'for NUM_LONGJMP_NAMES' loop would work nicely as
probes would work. 

The no changes were detected in the testsuite by moving the 'if' before
the 'for' compared to removing it altogether.

Regards,
Tiago
