Hi,

std.math.internal.gammafunction is the last module with failing
unittest on ARM, simply because it assumes that reals are always in
x86 extended precision format which is obviously not true on ARM.

I haven't got the required (maths) knowledge to fix this, so it'd be
very appreciated if somebody could take a look.

It's actually possible to easily test this on x86 with gdc: Just install
a recent gdc build and use the -mlong-double-64 command line argument.
