rS327530: The recent bump of MAXDSIZ made 32-bit binary execution on 64-bit powerpc fail.
Summary

The recent bump of MAXDSIZ made 32-bit binary execution on 64-bit powerpc fail. The data segement was too big.

Add a fix-up function like on ia32 for MAXDSIZ.

While here, bring also the MAXSSIZ closer to amd64 and add an equal fix-up function for MAXSSIZ.

Test Plan
  • gcc multilib bootstrap succeeded.
  • buildworld/kernel succeeded.
  • tested on 32-bit and 64-bit powerpc.
