[Minios-devel] [UNIKRAFT PATCH 06/23] kconfig: Removing the generic rule

[Sharan Santhanam <sharan.santhanam@xxxxxxxxx>]

The generic rule to build c and cc are no longer needed to build the
kconfig tools. It uses fixdep to determine if the config tool has to be
built and execute the build command as necessary.
