um: Build always with -mcmodel=large on 64bit
On UML SUBARCH can be x86, x86_64 and i386 and if it is x86 we use uname -m to select a defconfig. Therefore we can no longer use -mcmodel=large only if SUBARCH is x86_64. Reported-and-tested-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: Richard Weinberger <richard@nod.at>
