Will it still be possible to use a pre-existing x-compiler for target?

When building let's say 3 canadian-cross crompilers, fx.

i686-linux -> arm-linux
x86_64-linux -> arm-linux
mingw32 -> arm-linux

It would be nice to be able to not have to build the same target
x-compiler three times.

For the single canadian case, that is.

Nice.

But if you need more than one canadian-cross compiler...
