aarch64: support binary mode for opening files
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.
