Subject: powerpc: Fix -mcpu= options for SPE-only compiler
Forwarded: https://lists.debian.org/debian-kernel/2018/12/msg00295.html
GCC for Debian's "powerpcspe" architecture only supports 32-bit
SPE targets, and using -mcpu=powerpc or -mcpu=powerpc64 is a fatal
error.
* Change the test for a biarch compiler to pass both the -m32 and -m64
options, so that it doesn't catch 32-bit-only compilers
* Add an ifdef CONFIG_PPC64 around the 64-bit CPU option definitions
