Add -Wtrampolines to CFLAGS.
elfutils uses nested functions a lot. This is fine unless one takes the
address of such a nested function. When taking the address of a nested
function a trampoline is generated that on some systems require the stack
to be executable. That is bad. We never want to generate such trampolines.
Add -Wtrampolines to CLAGS to make sure we don't.
