Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System
Void 32-bit ARMv6 and ARMv7 versions of the Go compiler.
### Expected behavior
The Go compiler will use hardware float by default for 32-bit ARMv7 platform and maybe even the ARMv6 platform.
### Actual behavior
The Go compiler packages are built without specifying GOARM=7 or GOARM=6 and apparently default to ARMv5 compatibility.
### Steps to reproduce the behavior
Compile any program that uses floating point and check performance.
### Possible fix
The Alpine Linux build scripts case things as
```
armel) export GOARCH="arm" GOARM=5 ;;
armhf) export GOARCH="arm" GOARM=6 ;;
armv7) export GOARCH="arm" GOARM=7 ;;
```
which seems like a good idea to avoid everything defaulting to GOARM=5.

Comment:
Another work around is to set the environment variable
```
$ export GOARM=7
```
before compiling anything on the ARMv7 version of Void Linux.

Comment:
That should definitely be fixed. You can look into `common/environment/build-style/go.sh` to see how the setup works and tweak it.

Hm, are you sure?

How did you test this?
