(making dirs and links): If we already made subdirs
for a dir foo and foo turns out to be a symlink outside /usr/include,
after we have made a dir for it in ./root/, make similar subdirs there.

	now does the whole calculation, including rounding.
	(FUNCTION_PROLOGUE, FUNCTION_EPILOGUE): Don't pass leaf_function
	to output_function_{prologue,epilogue}.

	(compute_frame_size): Many changes. Return the total frame size,
	including space for "magic" stuff at the top of the stack and any
	rounding for the Snake.
	(output_function_prologue): Don't take a leaf_function argument;
	Decide that based on frame size and frame_pointer_needed.
	Don't emit any frame diddling code if actual_fsize is 0.
	(output_function_epilogue): Don't take leaf_function argument.
	Don't do anything if no frame.
	Keep stack pointer aligned to 64 bytes before loading from old
	frame pointer.

	have an empty delay slot to fill.
	(eligible_for_epilogue_delay): Don't check "leaf_function" anymore.
