Bug #14231: __uint128_t check in hash.c is broken, use

----------------------------------------
Current check for __uint128_t in hash.c is not valid, since it ignores
compilers other than gcc. We hit this on lcc on e2k platform.

Configure script properly checks from 128-bit data types support and
sets HAVE_UINT128_T accordingly. This approach is already used within
ruby at bignum.c, random.c, etc.

Probably hash.c is an overlooked remnant of old days. This patch fixes
this.
