Use UINT128_T support flag from configure
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.

From: Andrew Savchenko <bircoph@altlinux.org>
hash.c: use uint128_t
* hash.c (mult_and_mix): use uint128_t instead of __uint128_t.
