Apparently something in GCC or libc has changed recently at causes
binaries to contain debug info, even when they compiled without -g:
(stretch) $ gcc test.c && readelf --sections a.out | grep -c debug
0
(sid) $ gcc test.c && readelf --sections a.out | grep debug

Niels said on IRC that we could just remove that part of the test, as
the new test suite already covers the debug-file-with-no-debug-symbols
tag.
