Nobody yet decided that the system call interface would be the same on
i386 and on x86_64 :)
Most probably we'll need a different header, to put the trap number of
rax instead of eax, notably. And the systemcall instruction will most
probably not be an lcall.

This can be already fixed by shipping a different file in mach, as we'll
most probably want in the end anyway.
