This (and perhaps the previous gotools) patch broke Solaris bootstrap:
/vol/gcc/src/hg/trunk/local/libgo/go/net/tcpsockopt_unix.go:23:73: error:
reference to undefined identifier 'syscall.TCP_KEEPINTVL'
if err := syscall.SetsockoptInt(fd.sysfd, syscall.IPPROTO_TCP,
syscall.TCP_KEEPINTVL, secs); err != nil {
/vol/gcc/src/hg/trunk/local/libgo/go/net/tcpsockopt_unix.go:26:103: error:
reference to undefined identifier 'syscall.TCP_KEEPIDLE'
return os.NewSyscallError("setsockopt", syscall.SetsockoptInt(fd.sysfd,
syscall.IPPROTO_TCP, syscall.TCP_KEEPIDLE, secs))
make[4]: *** [net.lo] Error 1
The following patch fixes this:

Apart from that, bootstrap fails in gotools: due to the use of
-static-libgo, all commands there fail to link since the socket
functions are missing. It seems like $LIBS from libgo needs to be added
somewhere, but I'm unsure how best to handle this. To make any progress
at all, I've just manually added -lsocket -lnsl to gotools/Makefile
(AM_LDFLAGS).
