Yes. Nobody has done the effort on getting BR2_PACKAGE_GCC_TARGET to
work with external toolchain as of today. As said previously, Buildroot
is a cross-compiling environment, so the need of a toolchain on the
target is not very common.

Just curious, which toolchain have you used ?

Yes, correct.

It isn't set in the external toolchain case, that's the problem. I now
Gustavo Zacarias has planned to rework the gcc handling, and it should
probably fix this problem.

In the mean time, you can force the GCC version by modifying the code,
but you'll very likely have issues when building gcc for the target.

Do you really need a native toolchain on the target ? What do you want
to build on the target ?
