kbuild: support W=c and W=e shorthands for Kconfig
KCONFIG_WARN_UNKNOWN_SYMBOLS=1 and KCONFIG_WERROR=1 are descriptive
and suitable in scripting, but typing them from the command line can
be tedious.
Associate them with KBUILD_EXTRA_WARN (and the W= shorthand).
Support a new letter 'c' to enable extra checks in Kconfig. You can
still manage compiler warnings (W=1) and Kconfig warnings (W=c)
independently.
Reuse the letter 'e' to turn Kconfig warnings into errors.
As usual, you can combine multiple letters in KCONFIG_EXTRA_WARN.
$ KCONFIG_WARN_UNKNOWN_SYMBOLS=1 KCONFIG_WERROR=1 make defconfig
can be shortened to:
$ KBUILD_EXTRA_WARN=ce make defconfig
or, even shorter:
$ make W=ce defconfig
