Location to store binaries

[mcalhoun at macports.org]

As many of you know, the standard Rust compiler is self-hosting.
The upstream bootstrap compiler only works (unmodified) on 64-bit 10.9+.

There is an attempt to build a bootstrap compiler that runs on older
systems [1].
One stumbling block is where to build and store the bootstrap compilers.
I am afraid I know little about this.
Github packages, JFrog, other?
Does anyone have any suggestions?

Thanks,
Marcus
