Drop libtool from llvm.

We were only using it so find the shared library extension and nm. There are
simpler ways to do those things :-)

## (We might end up doing this anyway to support other compilers.)

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
