Cross-compiling with go for arm on amd64. Possible?

[Scott Aitken]

Hi,

So I wanted to install dns/dnscrypt-proxy2 on my Raspberry Pi running FreeBSD 
12.0-RELEASE r341666 GENERIC arm.

There's no package version, so I tried compiling. Unfortunately that didn't 
work as the Go dependency ran out of RAM compiling. And there's no package 
for Go...

So I fired up a VM and installed ports-mgmt/poudriere. Set it all up and 
added dns/dnscrypt-proxy2 to my shopping list...

Unfortunately it skipped lang/go:

Code:
[00:01:14] [01] [00:00:00] Building lang/go | go-1.13.4,1
[00:01:16] [01] [00:00:02] Finished lang/go | go-1.13.4,1: Ignored: fails to 
build with qemu-user-static
[00:01:16] [01] [00:00:02] Skipping dns/dnscrypt-proxy2 | 
dnscrypt-proxy2-2.0.31_1: Dependent port lang/go | go-1.13.4,1 ignored

Apparently Go 1.3 won't compile under the emulator (see PR 221297 for some 
background.

Is it possible for go to cross-compile for arm on amd64?

Thanks,
Scott
