[RFC] X86_64-elf port (part 1)

["Hans Kester" <kester dot hans at gmail dot com>]

Here is part 1 of a newlib port for a x86_64-elf target. As I am
totally new to automake, autoconf and other relevant tools I just
'hacked' the files that are normally generated by these tools. I am
sure someone can either tell me how to invoke the appropriate tools or
do it himself.

Since I don't have write access to the repository, perhaps someone can
commit this for me. After general approval that is.

Part 2 with the libc/machine/x86_64 directory will follow.

Regards,

Hans Kester
