[Buildroot] [PATCH] toolchain-external: remove sourcery powerpc toolchains

These are running long on the teeth - the bundled (e)glibc versions are
very old with several security bugs, they don't work reliably with -Os
and have several build failures related to internal compiler errors such
as:

http://autobuild.buildroot.net/results/fe7/fe7bdba5faf199275aedea2918705b5d19d228bf/
http://autobuild.buildroot.net/results/935/935ac42c30ed893939c06c077534f060aed80e9a/
http://autobuild.buildroot.net/results/a47/a476af82c8fe4a279117314b278b08af9a08fe54/
http://autobuild.buildroot.net/results/cae/cae720b5096be2672b4dc1311ae3fc4ed06a3b53/

The situation will not provide, and will in fact get worse with older kernel
headers precluding modern package versions and the old gcc version doing as
well so remove them.
