BUILD: debug: silence warning on gcc-5

In 2.6, 8a0fd3a36 ("BUILD: debug: work around gcc-12 excessive
-Warray-bounds warnings") disabled some warnings that were reported
around the the BUG() statement. But the -Wnull-dereference warning
isn't known from gcc-5, it only arrived in gcc-6, hence makes gcc-5
complain loudly that it doesn't know this directive. Let's just
condition this one to gcc-6.
