From cabae62b0ba1d31f524c393e294d3a5e08d543fc Mon Sep 17 00:00:00 2001

Subject: Add support for the FPA floating-point format on ARM. The FPA
 floating-point format is identical to the VFP format, but is always stored in
 big-endian. Introduce _IEEE_WORD_ORDER to describe the byte-order of the FP
 representation.
