Modules can choose to add "installed files", which are files that
a product can depend on to cause the module to build, and "checkbuild
files", which will only be built if another module that needs to build
depends on them. For every target, add a module-install and a
module-checkbuild target that create dependencies on those files,
and then add a global checkbuild target that depends on all the
module-checkbuild targets. Also add a module target for each module
that depends on module-install and module-checkbuild.
