netbsd-8 gcc gets Illegal instruction on R3000

[Izumi Tsutsui <tsutsui%ceres.dti.ne.jp@localhost>]

I've tried to build an application on NWS-3470D (R3000) running
NetBSD/newsmips 8.0, but gcc gets an illegal instruction error immediately:

---

% uname -mrs
NetBSD 8.0 newsmips
% sysctl -w hw.model
hw.model = news3400
% gcc --version
gcc (nb2 20180327) 5.5.0

Does anyone try gcc on NetBSD/mips 8.0 and R3000 hosts?

I wonder if there are still MIPS1 specific load delay botches
(I guess gxemul doesn't emulate it so that anita can't catch it).
