Thanks, now applied to trunk.  I forgot to say: this is a regression
from before MIPS GCC had explicit reloc support (3.3 and earlier),
so is it OK for the branches too, if testing goes OK?  (The same
test does fail for 4.2.  I haven't tried 4.1 yet, but that was
the version Kaz was using, so the bug definitely shows up for
4.1 somewhere.)
