toolchain/external: ensure gcc version is known 



Currently, when a preconfigured prebuilt toolchain forgets to specify
its gcc version, the error message is a bit misleading, like:

    Incorrect selection of gcc version: expected .x, got 4.9.2

Add a an explicit check for the gcc version being set, that reports a
better error message.
