BLD: Help raspian arm + clang 13 about `__builtin_mul_overflow`
It seems on raspian arm with clang 13 `__builtin_mul_overflow` is
defined for `int` but doesn't work for `ptrdiff_t` (and maybe others).
This checks for `ptrdiff_t` instead of int, which was reported to
work-around the issue.
Closes gh-22811
