James Tucker 538c2e8f7c tool/gocross: add debug data to CGO builds
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.

James Tucker 87f00d76c4 tool/gocross: treat empty GOOS/GOARCH as native GOOS/GOARCH
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.

David Anderson 17eae5b0d3 tool/gocross: force use of our custom toolchain
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.

Mihai Parparita bdc7a61c24 tool/gocross: add ts_macext build tag for Xcode builds
It's used to control various opt-in functionality for the macOS and iOS
apps, and was lost in the migration to gocross.

David Anderson 1f95bfedf7 tool/gocross: adjust Xcode flags to match new Xcode env
Xcode changed how/what data it exports to build steps at some point
recently, so our old way of figuring out the minimum support version
for clang stopped working.
