Thanks to the creator of the external toolchain option.
But I also have a difficulty.
I have set up the toolchain path and prefix, but there were problems finding
(kernel header?) files such as linux/param.h, since they aren't inside the
toolchain path.
I presume another include path needs setting up somewhere ... or a symlink ?
