When building the linux kernel for PPC_85xx cpus with GCC 8, the build fail with: powerpc-e500v2-linux-gnuspe-gcc: error: unrecognized argument in option '-mcpu=powerpc' powerpc-e500v2-linux-gnuspe-gcc: note: valid arguments to '-mcpu=' are: 8540 8548 native "GCC started treating "PowerPC" and "PowerPC SPE" as two different architectures and that's the reason for the reduced -mcpu list." [1] As suggested in the crosstool-ng issue [1], apply the Debian patch to avoid -mcpu=powerpc or -mcpu=powerpc64.
