Subject: [PATCH 3/3] SPEAr13xx_defconfig: Enable compilation using the latest

This Patch is to enable CONFIG_AEABI option in kernel. Which basically adds
support for latest ARMABI (EABI).

It also include support for changes the kernel syscall calling convention to
disambiguate both ABIs and allow for backward compatibility support.

Without this option the kernel crashes. Crash log is below:
