True, it's a bit ugly. True, the real culprit is the C library. But:
1. this is far from being written in stone. So I will add libc flavour
detection if and when needed.
2. you'd be surprised to see how old this is :) In 2008 I was working with this
on some old distributions (for that time).

What we really need is the conditional linking with -lrt (have it just on
Linux).
