Patch from Lennert Buytenhek

Hi,

gcc doesn't understand 80-bit floating point on the ARM currently,
according to the kernel's Kconfig docs, but it would seem that the
current extended double emulation code is broken for big endian
platforms.

So, this patch disables NWFPE_XP on big endian architectures, until
someone comes round and fixes it.


cheers,
Lennert
