Fix stack-protector for powerpc

On powerpc, stack protector expects a function called
__stack_chk_fail_local() instead of __stack_chk_fail()

And some versions of GCC for powerpc default to TLS canary
instead of global canary, so always force GCC to use global
canary with -mstack-protector-guard=global
