Cross compiling this program for linux/arm

package main

func main() {
    print("hello world\n")
}

Produces a warning

% GOARM=6 GOOS=linux GOARCH=arm go build -v hello.go
runtime
command-line-arguments
# command-line-arguments
warning: unable to find math.a

However the final binary still links and runs properly.

  1. The go tool, or linker should not produce a warning, it should be an error.
  2. math.a is being added to the dep chain unconditionally, see 891d344, but maybe this needs to be more nuanced.
