The problem is with CONFIG_CPU_BIG_ENDIAN=y we still needed .config
fixup to override the the defconfig prefix to arceb-linux-

So remove these from defconfig and let user pass this via CROSS_COMPILE
environment var or use the default for ENDIAN (per previous patch)

No other arch carries them in defconfigs anyways !

Even though DEVTMPFS is required when our pre-built initramfs
is used it is not the case in general. It is perfectly possible
to use initramfs with device nodes already populated or there
could be other usages, see discussion below for more detials:
http://thread.gmane.org/gmane.comp.embedded.openwrt.devel/37819/focus=37821

This change removes mentioned dependency from arch/arc/Kconfig
updating instead those defconfigs that are usually used with this
kind of pre-build initramfs.

And while at it all touched defconfigs were regenerated via
savedefconfig and some options were removed:
 * USB is selected by other options implicitly
 * VGA_CONSOLE is disableb for ARC since
   031e29b5
 * EXT3_FS automatically selects EXT4_FS
 * MTDxxx and JFFS2_FS make no sense for AXS because
   AXS NAND controller is not upstreamed
 * NET_OSCI_LAN is not in upstream as well
 * ARCPGU_xxx options make no sense because ARC PGU is not yet
   in upstream and when it gets there all config options would
   be taken from devicetree

When building kernel with buildroot built toolchain, CROSS_COMPILE
currently needs adjustment even if minor. This is because the defconfigs
prefer "arc-linux-uclibc-" prefix from hand built (non buildroot) toolchain
while buildroot provides "arc-buildroot-linux-uclibc-"

To avoid this use the common "arc-linux-" prefix which is provided by
buildroot and has also been in hand built tools for quite some time.

ARC GNU tools have had support for arc-linux-* driver for some time now.
This is functionally similar to arc-linux-uclibc-* but uclibc prefix
seemed weird at best when trying to compile the kernel itself.

symbol's entry was the only place were the symbols ARC_BOARD_ANGEL4 and
ARC_BOARD_ML509 were used. So ARC_BOARD_ANGEL4 and ARC_BOARD_ML509 can

This adds support for an ARC Virtual Platform. This platform is based on the
System C standard promoted by the OSCI (Open System C Initiative) and uses
nSIM to simulate the ARC CPU core itself.

Users can build a virtual SoC by combining System C models of peripherals
