Patch looks good to me. The story with floats is that on FreeBSD, the
i386 FPU is set to 53-bit floats, but the GNAT runtime library always
issues a "finit" instruction to reset it to full precision, so we need
to reset TARGET_96_ROUND_53_LONG_DOUBLE to 0.

John has been actively maintaining these changes for the past few years,
so I'm confident these files won't bitrot.
