In initial sun3x days, i.e. around NetBSD 1.2 in 1996,
NetBSD didn't have cross-build environment.

NetBSD 1.2 used customized gas (around 1.92.3?) for a.out
shared lib binaries, but kernel development people had to
prepare own cross build envronments from sources of
gcc (2.7.2.1?) and binutils (2.7?).

In these days, we have the same gas sources for both native
and cross build, so we can safely use gas-specific syntax.
