commit: https://git.buildroot.net/buildroot/commit/?id=a4ba0b7bf1aa647f1ec4cd0b01700a2d6d5456f8
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The oldest toolchain we test in the autobuilders is the Sourcery ARM
toolchain which is GCC 4.8 and kernel headers 3.13. Therefore, it is
likely that we're missing the required _AT_LEAST dependencies to exclude
packages that don't build with older GCC/headers.

Add a comment to the custom external toolchain that warns when an
untested GCC or kernel headers version is selected.
