[PATCH] Turn off sibling call optimization w/ frame pointers

Frame pointers are supposed to enable debuggers to reliably tell where a
call comes from.  That is defeated by GCC's sibling call optimization (aka
tail recursion elimination).

This patch turns this optimization off when compiling with frame pointers.
