modules: do not depend on kconfig to set 'modules' option to symbol MODULES
Currently, the MODULES symbol is special-cased in different places in the kconfig language. For example, if no symbol is defined to enable tristates, then kconfig looks up for a symbol named 'MODULES', and forces the 'modules' option onto that symbol. This causes problems as such: - since MODULES is special-cased, reading the configuration with KCONFIG_ALLCONFIG set will forcibly set MODULES to be 'valid' (ie. it has a valid value), when no such value was previously set. So MODULES defaults to 'n' unless it is present in KCONFIG_ALLCONFIG - other third-party projects may decide that 'MODULES' plays a different role for them This has been exposed by cset #cfa98f2e: kconfig: do not override symbols already set and reported by Stephen in: http://marc.info/?l=linux-next&m=137592137915234&w=2 As suggested by Sam, we explicitly define the MODULES symbol to be the tristate-enabler. This will allow us to drop special-casing of MODULES in the kconfig language, later. (Note: this patch is not a fix to Stephen's issue, just a first step).
