We use .gitignore these days.

Some tests rely on sort order and output of tools that might be localized.

GCC < 4.7 had a bug where no code CUs got a highpc == lowpc.
Allow that, because it is not the main purpose of this test.

readelf -d doesn't work if a SHT_NOBITS section is right before the actual
.dynamic section at the same offset. elflint also fails on such binaries.
So skip SHT_NOBITS sections at the same offset in [g]elf[32|64]_offscn().
