Not all assemblers support .loc markers, sometimes .debug_line is emitted by
gcc directly, and not all targets use dwarf. For the latter we can just put
the test into gcc.dg/debug/dwarf/, for the former we would need a new
dejagnu test. But more importantly, on different arches I'd guess the
number of .loc times might be different.
Better than that would be a guality testcase limited to -O0.
