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.

[Thomas:
 - remove no longer needed comment in liquid-dsp Config.in file, as
   noticed by Romain Naour.
 - add Config.in.legacy options, as noticed by Romain Naour.]
