[AArch64] Newlib/libgloss port for ARM's new 64-bit architecture, AArch64

[Yufeng Zhang <Yufeng dot Zhang at arm dot com>]

Following on from the recent publication of GCC and binutils ports, ARM 
is pleased to announce a port of newlib and libgloss to its AArch64 
architecture.  This completes the bare minimum support required for a 
bare-metal toolchain.

Please note that while the new port of the libraries has been used to 
build a large body of software, it should still be considered 
work-in-progress.  However, we believe that the code is sufficiently 
functional for many purposes.

The following target triplets have been tested using toolchains built on 
32- and 64-bit hosts:

- aarch64-none-elf
- aarch64_be-none-elf

The code is structured from the start to use libgloss; all the 
board-specific configuration is held there.  An initial configuration 
for the draft AArch64 RDI protocol is provided.

There is just one failure, newlib.locale/UTF-8.c, being reported from 
test-runs.  However, we believe this is a generic issue as the same test 
fails in many other target configurations.

A final warning, although the big-endian support here is as good as the 
little-endian support, GCC for big-endian is still definitely in 
development.


Thanks,
Yufeng
