The font drivers that are statically linked to the library at build time

is now managed through the file `config/<platform>/ftmodule.h', which is
automatically generated through the rules file `config/modules.mk'

Some changes to include this new rules file. Also, the target "modules"
will force the re-generation of the drivers list (this is handy when
adding or removing a font driver from the source tree).
