+Subject: [PATCH] powerpc: Fix -mcpu= options for SPE-only compiler
+
+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
