site/*-linux: don't cache ac_cv_sizeof_bool

The value was hardcoded from the time it couldn't be computed, which
is no longer the case. After C99 'bool' is only defined if stdbool.h
is included, it's implementation defined and not required to be 1, so
caching it doesn't make sense and certain recipes whoose code test
ac_cv_sizeof_bool fail to build.
