It certainly does seem odd that it was built with the floating point
hardware stuff compiled in, given that the unit has no floating point
support.  My hands are a bit tied in that I don't have control over the
toolchain, but I will bring it up with them.  If I have to, I suppose
I'll just have to stick with the 1.1.2 build, and figure out how to make
it work.
