Just call ${CT_TARGET}-strip :
  - if in cross-mode, then we can run it from the final installation
    location ${CT_PREFIX_DIR}/bin, which is in the $PATH
  - if in canadian-mode, then we can run it from the 'host' binutils
    that was build earlier, and isntalled in ${CT_BUILDTOOLS_DIR}/bin,
    which is also in the $PATH

Note: in cross-mode, both ${CT_PREFIX_DIR}/bin and ${CT_BUILDTOOLS_DIR}/bin
are in the $PATH, in this order, to give precedence to the final location
over the build-time-only tools. In canadian-mode, only the latter is in the
$PATH, so we do not even have the possibility to run host code.

Yann E. MORIN.
