This commit broke splitting the package into two outputs "out" and
"utils".

When everything is working, the utils output should look like this:

bug#50071: 02/02: gnu: syncthing: Prepare for cross-compiling.

[Leo Famulari]

Quoting from Efraim on #guix:

"the go cross-build error I was seeing is this: go install: cannot install cross-compiled binaries when GOBIN is set"

bug#50071: 02/02: gnu: syncthing: Prepare for cross-compiling.

Upstream gives instructions on how to cross-compile Syncthing:

------
`go run build.go build`

    Builds just the named target, or syncthing by default, to the
    current directory. Use this when cross compiling, with parameters
    for what to cross compile to: go run build.go -goos linux -goarch
    386 build.
