make: Add utilities.mak

Some features need to be tested on the system
where the crtools is compiled, in particular we
will need to know if prlimit is implemented.

The file is taken from kernel's perf tool code.
And adopted for our needs.

x86: Implement prlimit proxy

RHEL6 is shipped with libc 2.12 where no prlimit
helper provided (which was pushed into libc itself
since 2.13). So we implement own proxy for convenience.

Note, if libc does support prlimit itself we simply
don't use any proxy and call it directly.
