The check_unusable_toolchain helper is called in
TOOLCHAIN_EXTERNAL_CONFIGURE_CMDS, not when the sysroot is copied to
staging.

I think you should state that we can safely remove the checks in
TOOLCHAIN_EXTERNAL_INSTALL_* because the check is already done in
TOOLCHAIN_EXTERNAL_CONFIGURE_CMDS, so we now it is not needed to do it
again later.
