Fix debug_prefix_map failure with old objdump versions

“objdump -g” does not list debug info like the “Multiple
-fdebug-prefix-map” test expects when using objdump 2.20, e.g. on CentOS
6. “objdump -W” does however work, and it seems to work for object files
with compressed .debug_str section as well.

Related to issue #639.
