One of your very recent dwarf2dbg.c changes caused my cris-elf
autotester to buzz. Given the log message and a brief look in
that source file, I think it was this one. (There's more than
one return in remap_debug_filename.) The FAILs (well, the
lns.exp ones) should be visible for other targets. Host was
x86_64, F 12.
