Subject: [PATCH 1/2] sha512256: patch portability.h to compile on ARM

Intel's x86 intrinsics do not apply to ARM architectures (obviously!).

This patch only enables compilation: for optimum performance
architecture-specific bytecode should be implemented instead.

This should probably also be backported to other branches, such as 3.5.x
on which the current stable `npm` package (and, through that, Live)
depends.
