Incorrect selection of gcc version: expected 4.3.x, got 8.2.0

[freemp]

Here's what I did...

$ git clone git://git.buildroot.net/buildroot
$ cd buildroot
$ git checkout -b minimal 2018.02

From that point on I followed the instructions in the README. Running make results in this:

...
>>> toolchain-external-custom  Patching
>>> toolchain-external-custom  Configuring
Incorrect selection of gcc version: expected 4.3.x, got 8.2.0
make[1]: *** [package/pkg-generic.mk:240: /home/test/build/build/toolchain-external-custom/.stamp_configured] Error 1
make: *** [Makefile:16: _all] Error 2

What am I missing?

Indeed, I could reproduce your issue on a Ubuntu Bionic Docker, this is strange, I would need more testing and maybe update Buildroot.
Thanks for the report.
