Issue building go on docker arm/v/7 with alpine image

[niedfelj]

What version of Go are you using (go version)?

1.12.12-r0

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

What did you do?

Running into an issue compiling a program running under alpine/docker using the cross-platform version of docker (qemu). I've detailed everything on the balena forum with a repo that can be checked out.

https://forums.balena.io/t/cant-compile-golang-on-armv7-via-balena-cross-compile-or-docker-edge-arm-support/40591/2

What did you expect to see?

It should compile the program correctly. It works under Ubuntu on every platform/image. Works with Alpine images on actual armv7 hardware but not under docker/qemu on amd64/x86 hardware when trying to run arm images.

What did you see instead?

Everything I try to build gives an error similar to this:
