ARM: use CONFIG_AEABI by default everywhere

Browse Source 
On ARMv4 and ARMv5, the default is still to build for OABI, with
CONFIG_AEABI disabled, even though distros and toolchains no longer
support OABI as a target.

Change the default to EABI for all architecture levels and change
the defconfig entries as follows:

 - All machines that used to explicitly enable EABI can drop that line now
 - Machines that are likely to actually use old distros and had NWFPE
   enabled in combination with OABI (rpc, footrbridge, netwinder,
   assabet, neponset) explicitly turn it on now.
 - Machines that already had both EABI and NWFPE disabled in defconfig
   (spear3xx, spear6xx) were likely not usable with either OABI or
   EABI and now use EABI instead implicitly, making it more likely that
   they could work.

help
This option allows for the kernel to be compiled using the latest
ARM ABI (aka EABI). This is only useful if you are using a user
space environment that is also compiled with EABI.
The Arm EABI is the default ABI on all modern Linux
distributions, replacing the obsolete and "OABI" that was
commonly used on ARMv4 distributions before ca. 2013.
Since there are major incompatibilities between the legacy ABI and
EABI, especially with regard to structure member alignment, this
option also changes the kernel syscall calling convention to
disambiguate both ABIs and allow for backward compatibility support
(selected with CONFIG_OABI_COMPAT).
Everyone should enable this, as support for OABI user space
was dropped in gcc-4.8 and most distributions after ca. 2013.
config OABI_COMPAT
bool "Allow old ABI binaries to run with this kernel (EXPERIMENTAL)"
