Ok, thanks for patch. I should probably add a little bit of error
checking in this external toolchain thing.

Which doesn't exist anymore since it has been merged in the official
Buildroot :-)

But ok, fine, I know what you're using.

For sure if Buildroot didn't properly copy the sysroot to the staging
dir, the rest of the compilation could not work.

That said, your configuration file enables a relatively large set of
packages that I haven't tested with the external toolchain
configuration. Most if not all of the packages using the
Makefile.autotools.in machinery should build flawlessly, but the
packages using their own stuff in the .mk might break. Don't hesitate
to report the breakage with the associated error messages (or the full
build output), it's usually relatively easy to fix.

Thanks!
