Before adding gcc 9.1 [1] to Buildroot, add some fixes for issues discovered
by toolchain-builder [2] that are trigged by this new compiler version.
(disable powerpc Werror, uClibc-ng asm sparc and ARC glibc).

Then add gcc 9.1 for internal and extenal toolchain backend and switch gcc 8.x
as default compiler.

Thanks to Yann E. MORIN for providing a patch series that add new ARM cores
added by gcc 9.1.

Each new ARM core has been build tested for aarch64:

Finally, enable the new ork1 (openrisc) that will replace in the following
series the old gcc fork (gcc 5.x).
