I took a spin at building Firefox last year, and while I didn't get a
complete build finished (ran out of time) it was honestly easier to
get master to build than ESR.  The main branch usually uses updated
crates, and thus tends to have _better_ support for illumos than the
older ESR branches.

The old "sun-solaris" targets are not really being maintained by the
illumos community at this point -- either in the Rust toolchain
itself, or in the crates in the Rust ecosystem at large.  I would
recommend using the illumos target and getting any build issues fixed
upstream in whatever crates have remaining platform-specific issues.

I and some other folks have been doing that sort of thing a lot
throughout 2019-2020.  Most or all of our patches and testing are for
the illumos target, even if the Solaris targets sometimes also come
along for the ride.

I think it'd be best if OI ships an illumos target toolchain for Rust,
rather than the increasingly obsolete solaris target.  Then we're all
testing and working on the same bits!


Cheers.
