PATCH: Add sysdeps/unix/sysv/linux/x86_64/x32/configure.in

[H.J. Lu]

Hi,

This patch adds sysdeps/unix/sysv/linux/x86_64/x32/configure.in
to specify minimum kernel and directories for x32.  I used 2.6.39 as
minimum kernel since Fedora 15 kernel maps kernel 3.x to 2.6.4x.y.
OK to install?

Thanks.

H.J.
