New target: x86_64-pc-cygwin

[Corinna Vinschen <vinschen@redhat.com>]

Hi guys,

now that the binutils patches are applied, I'd like to add the new
x86_64-pc-cygwin target to GDB.  What's still missing are the GCC
patches, but they will have to wait for the next GCC stage1.

Ok to apply?


Thanks,
Corinna


	* configure.host: Add x86_64-*-cygwin* as host.
	* configure.tgt: Add x86_64-*-cygwin* as target.
	* config/i386/cygwin64.mh: New file.
	* gdbserver/configure.srv: Add x86_64-*-cygwin* as target.
