Enabling GCC-8.x with support for BR2_powerpc_8548 cores

The GCC-7.x compiler series was the last to support BR2_powerpc_SPE CPUs
within GCC.  After GCC-7.x support was removed as a default in buildroot,
some boards, including the arcturus_ucp1020_defconfig and
freescale_p1025twr_defconfig will fail to compile.

The GCC-8.x compiler series continues to support powerpc_8548 CPU
cores, but only as an --enable-obsoleted instruction set. 
This patch is enables the use of GCC-8.x and asserts the required
option to enable the powerpc_8548 instruction set for the 
arcturus_ucp1020 platform.

This Patch passes compilation and run tests with the arcturus/ppc-ucp1020
board.  This patch should address a noted job failure on GitLab CI
https://gitlab.com/buildroot.org/buildroot/-/jobs/779210821
