test run-make/atomic-lock-free fails on i686 linux

I looked into it and it seems the reason is that gnu binutils is not compiled with --enable-targets=all on my system (default arch install). This means that nm is not able to read symbols from x86_64 binaries and so the test fails.

Seems odd to have a dependency on the way binutils was compiled, especially one where for a major distro it is not set by default.

We probably should just use objdump, as it, in my experience, cares less about formats and whatnot.

I have my own binutils installed with --enable-targets=all but it still fails.

Going to close this is "probably fixed" - not even sure how to begin to dig into this.
