Adding additional cross-compiling ports?

[kraileth]

Just throwing in an idea: AFIK gnatcross-bootstrap is the only port we have right now which makes use of one of the cross toolchains that ravenports has to build a native compiler for the respective platform. I wonder if it would make sense to add other such ports (zlib, zstd, etc.) providing the dependencies (static libs mostly) for rvn (or probably one big rvn-bootstrap port which builds all of these as well as rvn using the existing cross toolchain? Given that the toolchain exists, this can probably be generalized enough to make any future bootstrapping of the package manager from an existing foreign platform much easier - or can't it? If it is feasible, ravenadm-bootstrap might be another such candidate, of course. Again, just a thought.
