linux-yocto/3.4: add x32 configuration fragment

When x32 is the tuning for a x86 MACHINE, the kernel should also have
CONFIG_X86_X32=y. This adds a x32 fragment that can be used to trigger
the right ABI.

The commit also contains a check for mx32 in TUNE_FEATURES, and if
present, the new fragment will be appended to KERNEL_FEATURES and
trigger the support in the kernel.
