Subjectseccomp selftest fails to build with glibc 2.26
Hi Kees,

I'm seeing build failures with your seccomp selftest when using glibc
2.26. The first are related to changing macro names from __have_sig*_t
to __sig*_t_defined. But after defining those there are more conflicting
definitions. I was able to get it to build with the changes below,
however it's ugly so I'm hesitant to suggest that it's a fix (and I
haven't tested with older glibc either).

The full build output is a little lengthy, so I've pasted it at
http://pastebin.ubuntu.com/25486192/ rather than including it inline.

Thanks,
Seth
