Oh I see. CT_TARGET (the tuple) is set internally by crosstool-NG during
the build. This means that:
- you do not have to provide it to crosstool-NG
- once crosstool-NG finishes, the variable is no longer set

So you can not use the CT_TARGET variable.

For my part, all my toolchains are installed in a specific place, so I put
this in my .bashrc:
  for d in /opt/x-tools/*/bin; do
    [ -d "${d}" ] && PATH="${PATH}:${d}"
  done
  export PATH

This way I do not have to care what toolchains are installed, and what the
tuples are. They will always be in the PATH.

Of course, that rules out having two toolchains with the same tuple, but in
this case you are just asking for trouble! ;-)
