8cba5463de support/scripts/gen-bootlin-toolchains: do not assume RPC for glibc toolchains
The logic in gen-bootlin-toolchains was assuming all glibc toolchains
have RPC support, which is no longer true since glibc 2.32 has dropped
RPC support.

It turns out that gen-bootlin-toolchains already had some proper logic
that selects BR2_TOOLCHAIN_HAS_NATIVE_RPC depending on the presence of
BR2_TOOLCHAIN_EXTERNAL_INET_RPC in the toolchain fragment. As such
toolchain fragments have been fixed in https://toolchains.bootlin.com,
we can now rely on this to properly decide if the toolchain has RPC
support or not.

1f3e5e6b3d support/scripts/gen-bootlin-toolchains: add support for more PowerPC toolchains
The 2020.08-1 release of Bootlin toolchains has brought support for 3
additional architecture variants, so let's support them.

glibc toolchains must be disabled for static only configuration.

184d47a7ad support/scripts/gen-bootlin-toolchains: add new script to support Bootlin toolchains
https://toolchains.bootlin.com/ has been providing for a few years a
number of ready-to-use pre-built toolchains, for a wide range of
architectures (which it turns out, are all built using Buildroot).

While toolchains.bootlin.com provides Buildroot config fragments to
easily use those toolchains with Buildroot (see [0] for example), this
is not visible anywhere. So instead, we would like to add support for
these toolchains in Buildroot just like we have existing support for
Linaro, ARM, Synopsys, etc. toolchains.

[0] https://toolchains.bootlin.com/downloads/releases/toolchains/aarch64/fragments/aarch64--glibc--bleeding-edge-2020.02-2.frag

However, the number of toolchains provided by toolchains.bootlin.com
is really large, and they are regularly updated. Maintaining that
manually would be time consuming and error-prone. So instead, this
commit introduces a script that automatically generates:

 - toolchain/toolchain-external/toolchain-external-bootlin/Config.in.options
 - toolchain/toolchain-external/toolchain-external-bootlin/toolchain-external-bootlin.mk
 - toolchain/toolchain-external/toolchain-external-bootlin/toolchain-external-bootlin.hash
 - support/testing/tests/toolchain/test_external_bootlin.py

We create a single external toolchain package, with a Kconfig "choice"
as a sub-option to select the toolchain variant to be used. The script
contains a Python dict that provides the mapping between the
toolchains provided by toolchains.bootlin.com, and the architecture
options/variants they are applicable to.

The test cases allow to verify that the toolchain configuration is
correct, and that it is able to build a Busybox based system. It
doesn't do any runtime testing as such testing is already done by
toolchains.bootlin.com: the test cases here are only meant to verify
that the toolchain-external-bootlin package works as expected.
