Authentication-results: sourceware.org; auth=none

The attached change fixes a regression in the debug/backtrace-tst test.  It tightens up the checks
for a valid function pointers.  It also uses the proberi instruction to avoid faulting when the address is
not a valid function pointer.  However, it's probably not possible to completely ensure that the address
lookup is correct given an arbitrary address.

Please install if okay.
