Fix regression from #8108 (Mar 2023). Since that change, gocross has
always been rebuilt on each run of ./tool/go (gocross-wrapper.sh),
adding ~100ms. (Well, not totally rebuilt; cmd/go's caching still
ends up working fine.)
The problem was $gocross_path was just "gocross", which isn't in my
path (and "." isn't in my $PATH, as it shouldn't be), so this line was
always evaluating to the empty string:
gotver="$($gocross_path gocross-version 2>/dev/null || echo '')"
The ./gocross is fine because of the earlier `cd "$repo_root"`

We don't build a lot of tools with CGO, but we do build some, and it's
extremely valuable for production services in particular to have symbols
included - for perf and so on.
I tested various other builds that could be affected negatively, in
particular macOS/iOS, but those use split-dwarf already as part of their
build path, and Android which does not currently use gocross.
One binary which is normally 120mb only grew to 123mb, so the trade-off
is definitely worthwhile in context.

Tracking down the side effect can otherwise be a pain, for example on
Darwin an empty GOOS resulted in CGO being implicitly disabled. The user
intended for `export GOOS=` to act like unset, and while this is a
misunderstanding, the main toolchain would treat it this way.

The new 'toolchain' directive in go.mod can sometimes force
the use of an upstream toolchain against our wishes. Concurrently,
some of our dependencies have added the 'toolchain' directive, which
transitively adds it to our own go.mod. Force all uses of gocross to
ignore that directive and stick to our customized toolchain.

This builds the assets for the new web client as part of our release
process. The path to the web client source is specified by the
-web-client-root flag. This allows corp builds to first vendor the
tailscale.com module, and then build the web client assets in the vendor
directory.
The default value for the -web-client-root flag is empty, so no assets
are built by default.

When running in our github CI environment, curl sometimes hangs while closing

The subshell in which gocross gets built cd's to the corp checkout dir
near the top, so all future references to corp repository files should
be simple relative paths, and not reference $repo_root. When $repo_root
is an absolute path, it doesn't matter and everything works out, but on
some OSes and shells and invocations, $repo_root is a completely relative
path that is invalidated by the "cd".

Previously, the build ended up embedding an empty string, which made
the shell wrapper rebuild gocross on every invocation. This is still
reasonably fast, but fixing the bypass shaves 80% off gocross's overhead
when no rebuild is needed.

A bunch of us invoke tool/go from outside the repo that hosts gocross,
as a way of accessing our version-controlled toolchain. This removes

Sometimes, our cached toolchain ends up being an older version of
Go, older than our go.mod allows. In that scenario, gocross-wrapper.sh
would find a usable toolchain, but then fail to compile gocross.
This change makes the wrapper script check that the cached toolchain's
minor version is good enough to build tailscale.com, and re-bootstraps
in shell if not.

We need to build gocross from multiple repos, but Go's innate
git hash embedding only works when you build gocross from this repo,
not when you build it from elsewhere via 'go build

found with 'git rev-parse HEAD', which will work from any git repo.

Saves about 1.4MB from the generated wasm file. The Brotli size is
basically unchanged (it's actually slightly larger, by 40K), suggesting
that most of the size delta is due to not inlining and other changes
that were easily compressible.
However, it still seems worthwhile to have a smaller final binary, to
reduce parse time and increase likelihood that we fit in the browser's
disk cache. Actual performance appears to be unchanged.
