Replace which by bash-builtin hash

Reportedly, which is not installed by default on all non-windows
systems bazel is used. As we only use which to test if a program
can be found on PATH, use the bash builtin hash command. While there
- replace the search for [ by a search for tr, a program we care more,
  as [ is the builtin test anyway,
- fix a typo in the name of the GNU tools collection searched for.
