The support for __uint128_t is dependent on the target bit size.
GCC that defaults to the 32-bit can still build the 64-bit kernel
with -m64 flag passed.
However, $(cc-option,-D__SIZEOF_INT128__=0) is evaluated against the
default machine bit, which may not match to the kernel it is building.
Theoretically, this could be evaluated separately for 64BIT/32BIT.
config CC_HAS_INT128
bool
default !$(cc-option,$(m64-flag) -D__SIZEOF_INT128__=0) if 64BIT
default !$(cc-option,$(m32-flag) -D__SIZEOF_INT128__=0)
I simplified it more because the 32-bit compiler is unlikely to support
__uint128_t.
