powerpc: Fix up elf_read_implies_exec() usage
We believe if a toolchain supports PT_GNU_STACK that it sets the proper PHDR permissions. Therefor elf_read_implies_exec() should only be true if we don't see PT_GNU_STACK set. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
