On MMU, we unconditionally build module.c.

On nommu, it depends on CONFIG_MODULES.
However, most inside module.c is already protected by #ifdef CONFIG_MODULES.
Except for module_fixup(), which is empty for nommu. After moving the whole
module_fixup() inside #ifdef CONFIG_MMU, you can consolidate the module.o
entry in the Makefile.
Actually you don't even need to modify module.c to always build
at the moment. I can move to always building module.o, it costs
an extra 2 bytes in the final non-MMU/no-modules case :-)

Greg
