Adding hurd to unixsock_readmsg_cloexec.go fixes the build of libgo

Hello,

The attached patch fixes the build of libgo for GNU/Hurd for gcc-12-20220126
when patching the generated libgo/Makefile as follows:

change
../libbacktrace/libbacktrace.la
to
../../libbacktrace/libbacktrace.la

and remove libatomic from the linkage:
LIBATOMIC =3D ../libatomic/libatomic_convenience.la
PTHREAD_CFLAGS =3D -pthread -L../libatomic/.libs
since libatomic is not built yet. It should built before libgo but does not.
Unknown why, it may be a problem with the Debian stuff.

Additionally, continuing, the build of gotools fails:
go1: error: '-fsplit-stack' currently only supported on GNU/Linux
go1: error: '-fsplit-stack' is not supported by this compiler configuration

The reason for this also unknown so far, libgo and gotools built fine with
split-stack on gcc-11.=20

Is this problem related to that libatomic not yet has bee built??

Thanks!=
