[AD] makefile targets fix

[Elias Pschernig <elias@xxxxxxxxxx>]

I finally realized what had often caused strange and unexplainable bugs
while working on the allegro code - there was a missing dependency for
the install-lib target. So with enabled modules, it would not update the
modules.

The patch fixes this, and also adds two targets to the docs, which are
quite useful, at least when modifying allegro's code.
