Thanks very much for your hint. Inferno's 0l uses fnuxi4, whereas its vl
uses fnuxi8, just like Plan 9's. I adopted the Inferno 0l's way, and added
one line in obj.c to set fnuxi4 for BE, as well as the corresponding debug
output. This seems to work with both BE and LE. For BE it gives the same
output as before.

diff /sys/src/cmd/vl/asm.c ./asm.c
672c672
<                     buf.dbuf[l] = cast[fnuxi8[i+4]];

Does this break anything? If not, I will submit a patch.
