[committed] aarch64: support binary mode for opening files

[Richard Earnshaw]

Newlib for aarch64 uses libgloss for the backend.  One common libgloss
implementation is the 'rdimon' implementation, which uses the Arm
Semihosting protocol.  In order to support a remote host that runs on
Windows we need to know whether a file is to be opened in binary or
text mode.  That means that we need to preserve this information via
O_BINARY until we know what the libgloss binding will be.

This patch simply copies the arm implementation from sys/arm/sys and
puts it in machine/aarch64/sys, because we don't have a 'sys' subtree
on aarch64.
