Bug#956820: gccgo does not implement syscall in hurd-i386

[Pirate Praveen]

Package: gccgo-9
Version: 9.3.0-9
Severity: important
X-debbugs-cc: debian-hurd@lists.debian.org
golang-github-nsf-termbox-go is failing to build with gcc-go (changed 
Build-Depends to golang-any and built on hurd-i386 latest sid).

There are many failures like this,

src/github.com/nsf/termbox-go/termbox.go:507:37: error: reference to 
undefined identifier ‘syscall.SYS_FCNTL’ 507 | r, _, e := 
syscall.Syscall(syscall.SYS_FCNTL, uintptr(fd), uintptr(cmd),
    | ^
src/github.com/nsf/termbox-go/termbox.go:50:17: error: use of undefined 
type ‘syscall_Termios’
 50 | orig_tios syscall_Termios

$ go version
go version go1.12.2 gccgo (Debian 9.3.0-9) 9.3.0 hurd/386

Discussion with hurd maintainers 
https://lists.debian.org/debian-hurd/2020/04/msg00026.html

Full build log attached. I think gccgo needs to implement these syscall 
interfaces for hurd.
