[RFA] Moving x86-64 configuration to separate directory

- Organization: SuSE CR
Hi,
I'm about to move all x86-64 configuration stuff to a separate
directory. For now it resides in config/i386 but AFAIK this is a relict
of cloning the the files from eachother, not the necessity.
Yet more x86-64 is definitely a different architecture than i386 :-)
Can I commit these patches? I tested them on native x86-64 as well as
for cross-targetted gdb.
Michal Ludvig
