feature request: support build output dir/platform

[automaticgiant]

i use something like

#!/usr/bin/env bash
set -o errexit
set -o pipefail
set -o nounset
IFS=$'\n\t'
# shellcheck disable=SC2154
trap 's=$?; echo "$0: Error on line "$LINENO": $BASH_COMMAND"; exit $s' ERR

exec 2>&1

gofmt -e -s -w *.go

mkdir -p bin

function build {
  echo building for $GOOS-$GOARCH
  go build -o bin/controller-$GOOS-$GOARCH controller.go
}

it's just what i made - idk what i'm doing.

anyway, that's good for building artifacts taht i include in gh releases or whatever.
it would be super cool to add an output dir flag to zb build so i wouldn't have to backport the stuff that adds the ldflags for commit/builddate.

the goos and goarch already pass through, so i have no problem building for other platforms, but i'd like to be able to specify like --outpattern bin/%name-%GOOS-%GOARCH or something.

it's also very possible that this is doable with no modification, but idk how. perhaps this is just a docs fix.

thanks for your consideration. also i really like zb so far.

That’s a very interesting feature request. Generally, I prefer to defer to the underlying go command for handling cross platform builds, but I do think there may be a use case here.
