config.mk: use memoization in cc-option macro to speed up compilation

Apply memoization to cc-option macro by caching the results of the
gcc calls. This macro is called very often so using cached results
leads to faster compilation times.

The old behaviour can be restored by defining the config option
CONFIG_CC_OPT_CACHE_DISABLE=y.
