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).
