Please try this patch; I've had it around for a while for what looks like
a similar problem on m68k-uclinux but haven't got round to doing the
necessary regression testing (and didn't know the bug in question was a
regression, or have a reduced testcase). (Is it a regression? That bug
isn't marked as such, and only regression fixes are going on trunk at
present.)
