Exactly!

Perhaps we should just push for 5.1.0 everywhere ;-P

Otherwise, we could still have `min-tool-versions.sh` with something like:

    $ cat scripts/min_versions/gcc
    4.9.0
    $ cat scripts/min_versions/gcc_arm64
    5.1.0
    $ cat scripts/min-tool-versions.sh
    if min_versions/$tool_$arch exists
        print that one
    else
        print the default one: min_versions/$tool

i.e. having the plain files allow us to extend the cases without
listing them explicitly in the script, plus it is anyway useful to
separate data from code :-)

Cheers,
Miguel
