When i'm building in the build system i will always be using absolute
paths to put the files in the right place. For instance for /usr/bin/app
it will do -f $RPM_BUILD_ROOT/usr/lib/debug/usr/bin/app.debug. So we will
leak some strange absolute paths. Of course, if gdb used the basename
when searching the global directories that wouldn't affect the result, but
it is sort of ugly.
