Testsuite: Skip failing tests on PowerPC 64-bit
The Power ISA says the result of a division by zero is undefined. So
ignore stdout on PowerPC 64-bit systems.
Disable ext-interp tests on 64-bit PowerPC. We don't have support for
PowerPC 64-bit ELF in the RTS linker, which is needed for the external
interpreter.
Test Plan: ./validate
