I really like this idea, those 4 ports compile/run fine on amd64, and
build fine on arm64.
With those new ports + patch, I have a working build of Fx 99.0.1 with
wasi sandboxing here on my amd64, no difference noticed so far.
I'm about to test this on arm64 but there doesn't seem to be
pre-compiled package for rust, so that will take some time as that
arm64 box will have to compile a lot of things...
After checking a few AUR packages, I think the current compiling setup
is alright, pulling the whole LLVM tree is probably the only way to do
it.
