Arch Linux

Description:
`go version` just reports "go version unknown linux/amd64" which breaks version checks

Additional info:
* package version(s) 12.1.0-1
* config and/or log files etc.

This is a regression, as older versions correctly reported the version number:

Steps to reproduce:
- Install package
- Run `go version`


If I try to build a program with gcc-go:

With gcc-go 11.2.0-4:

```
$ make build
go version go1.16.5 gccgo (GCC) 11.2.0 linux/amd64
bin/check_go_version 1.17
fatal: go version '1.16.5' should be at least '1.17'
=> Please take a look at https://golang.org/doc/install to install or upgrade go.
make: *** [mk/golang.mk:80: check_go_version] Error 1
```

With gcc-go 12.1.0-1:

```
$ make build
go version unknown linux/amd64
bin/check_go_version 1.17
fatal: Invalid 'go version' output: go version unknown linux/amd64
make: *** [mk/golang.mk:80: check_go_version] Error 1
```
