Control: retitle -4 mozjs52: FTBFS on s390x, powerpc64 (64-bit BE) with same tests failing

Unfortunately mips has new and exciting failures, and lots of them:

% grep -c UNEXPECTED-FAIL ../mozjs52.log
4913

so is in a considerably worse state than s390x or the powerpc family.

Cloning the bug to divide up the equivalence classes of architectures.
