[ARM] 3118/1: fix and reenable nwfpe extended precision emulation for big-endian
Patch from Lennert Buytenhek
nwfpe extended precision emulation used to be broken on big-endian
and was therefore disabled. This patch fixes nwfpe so that it copies
extended precision floats to/from userspace in the proper word order
(similar to patch #2046, see the description of that patch for an
explanation) and reenables the Kconfig option.

Say Y to include 80-bit support in the kernel floating-point
emulator. Otherwise, only 32 and 64-bit support is compiled in.
