I did a shell check on this script,

shellcheck -f gcc binutils-version.sh

The main issue is quoting of the 'sed' expression.  We had regex [0-9.],
but we want [0-9\.] so that we match a literal '.' as opposed to
anything.  Or so I speculate.  I made a script that output the version
info Hans has and after the patch it is fine.
