I like this name, adopted! :-)

Yes, I know this is a problem with the current autobuilders. My plan is
to make the tarballs of those external toolchains available somewhere,
so that people can easily install them as well. But that will take a
bit of time, and still leave some work when you want to reproduce a bug
(download the external toolchain, download .config, adjust .config to
match the path of the external toolchain on your local machine, build).
Or maybe, I should put all of them somewhere, and have my defconfig
download them from this common place. This could be a good idea to make
it easier to reproduce the build problems.

Also, there is a problem with BR external toolchains that are not (yet)
relocatable. I can create a tarball for them, but it will force you to
install them to /home/test/toolchains/... which is the location where
they are built on my build server. I guess the best solution for this
is just to make Buildroot toolchains relocatable :-)

Best regards,

Thomas
