Fix the bsymbolic_functions test and improve the error reporting

Browse Source 
The bsymbolic_functions test was missing $SYSROOT_FLAG, so the linking
was always failing and the test falsely negative.

Also make the error reporting better: if the flag was requested, error
out if the check fails and report more information in -v mode.
