nick black left as an exercise for the reader:
this wasm file is, again, distributed with the zig-bootstrap and zig sources.
it is a binary and knocks us out of main. this file can be recreated, using
sources from within the zig repository, with a working zig. but even the
"zig-bootstrap" source cannot move forward without either this file or
a working zig with which to create it ("zig-bootstrap" is more about
vendoring LLVM).
i looked at a few other distros:
- arch just builds it and is done with it
- guix, from what i can tell, is picking up a previous zig build of
their own and using that to bootstrap. i am 0% certain of this
interpretation [0].
- fedora looks promising; they certainly remove zig1.wasm before
building; i will examine this further.
From what I understand talking to upstream, we don't actually need
zig-boostrap at all. You can get a zig compiler up and running from only
even the zig upstream source.
The problem is that that repo contains a rather large amount of embedded
files. The people who initially tried to package this for Debian
struggled quite a bit, as you can see in the ITP:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=995670
Fortunately, those embedded files aren't needed for the core compiler
(called the stage2 compiler, which eventually builds the full zig
tool/compiler). This stage2 compiler *should* be enough to compile other
upstream projects written in zig too, so my intention is to upload this
to main as zig-minimal, which *should* be enough at least in terms of
building zig stuff that we want in the archive (upstream themselves
sound a little unsure about this... and said that we should test a few
upstream projects with it).
I broke my local build last when I worked on it, going to poke a bit at
it now, but my work so far is at:
https://salsa.debian.org/debian/zig
I strip out all the vendored stuff in debian/copyright:
https://salsa.debian.org/debian/zig/-/blob/main/debian/copyright?ref_type=heads#L5
That makes it really easy to upload a dfsg-free version that is somewhat
useful.
Also, apologies for any typos / nonsensical grammar here, been a long day :)

PS: also, bad bad bad nick for planting a will smith song in my head!
