[Buildroot] [PATCH v5 06/13] configs: add autobuild toolchain defconfigs

[Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>]

We currently have a list of toolchain configurations that are used by
the autobuilders at [1]. However, this makes it a little more difficult
for people to use these configurations, and also to have a different
list of configurations for different branches. For example if a new
architecture is introduced, the 2017.02.x branch doesn't have support
for this architecture yet so it shouldn't try to run those configs.

Therefore, include the autobuild defconfigs directly in Buildroot, so
they can be branched together with the rest. To avoid polluting the
configs/ directory too much, the autobuild defconfigs are kept in an
"autobuild" subdirectory.

Generated with
wget -nd --no-parent --recursive http://autobuild.buildroot.net/toolchains/configs/
mmv '*.config' '#1_defconfig'

The toolchain CSV file [1] contained some additional information, but
this information turns out not to be needed.

- The hostarch required by the toolchain binary. This is used by the
  autobuild script to avoid trying a toolchain that it cannot use.
  However, it is better that the autobuild script instead just checks
  if all the options specified in the toolchain config are still
  selected after creating a full config, like is done in the test-pkg
  script. That's much more robust against other things that might
  block a toolchain from being used.

- The libc used. This is used only for one thing: to let the
  autobuild script decide if it should try to enable BR2_STATIC_LIBS
  or not. However, that line can just be added unconditionally: for
  glibc toolchains, it will get removed again, no harm done.

v2: Refresh after rebuild of the br-* toolchains
    Don't add HOSTARCH, it's not needed as explained above

Note: I choose to name them xxx_defconfig and put them under to configs
directory so they can be used directly as a quick way to set up a build
with an external toolchain. However, neither test-pkg nor autobuild-run
will use them as _defconfig, so we could just as well call them *.config
and put them under e.g. support/autobuild-toolchains. Let me know what
you think.
