GH-113655: Lower the C recursion limit for all big-endian platforms

We currently reduce the C recursion limit just for s390x (which is big-endian),
but in Gentoo, we hit the same issues on ppc64be, hppa, and sparc.

At least for ppc64, it seems like the ABI used on ppc64be means you end
up with bigger stack frames.

Just set it to a sensible, conservative value for all BE platforms.
