The powerpc*-*-*spe* support has been deprecated in GCC 8 [1] and has been removed in GCC 9 [2]. While building with GCC 8, the build stop since we don't provide --enable-obsolete option. For now, keep powerpcspe support in Buildroot but only for older compiler up to GCC 7. Note: Although we can't select Glibc for powerpcspe since commit [4], this support has been removed for the next version of Glibc (the upcoming 2.30).
