Looks promising. A few questions:
- In my case I have what is essentially a supported platform but needs
to select a set of build tools with a different prefix. From looking
at the current diff of that pr, it appears I'll need to create a json
file that copies a bunch of values I don't really care about from an
existing target (with no automated way of extracting that json from
the existing target) just to change the value of the linker.
- Is the linker ("cc", presently) the only target build tool needed
when building the cross compiler?
I suppose the other piece of this is how well cargo handles cross
compiling things and what target tools it needs.
