[Buildroot] [PATCH] toolchain/custom: hide away incompatible gcc versions

Some CPUs have a requirement on a minimal gcc version. Until now, ot was
possible to use a custom external toolchain that has a gcc older than
the requirement, which would lead to build failures (early!) during the
build.
Propagate the gcc version requirement down to the external toolchain gcc
version choice. By limiting the selection to acceptable gcc versions, we
inform the user that its toolchain is too old, and if they decide to lie
and select one of available version, we still check that when we extract
and install their toolchain.
