[Buildroot] EABI option required ?

 I am trying to build a toolchain using buildroot and use that toolchain
to build
 Kernel and ramdisk for ARM 926EJ-Sid.

Is EABI option for toolchain required ?
 I used option OABI -- resulting in my shell not working.( Kernel comes
up but linuxrc does not execute. Seems that shell does not execute.).
> # BR2_ARM_EABI is not set

 If I use option EABI, then the kernel does not compile:
< # BR2_ARM_OABI is not set

Kernel compile Gives following error:

[root at raes linux-feroceon_2_2_2_NAS_GDP]# make uImage
  CHK     include/linux/version.h
  UPD     include/linux/version.h
  SYMLINK include/asm -> include/asm-arm
  SPLIT   include/linux/autoconf.h -> include/config/*
  CC      scripts/mod/empty.o
cc1: error: invalid option `abi=aapcs-linux'
make[2]: *** [scripts/mod/empty.o] Error 1
make[1]: *** [scripts/mod] Error 2
make: *** [scripts] Error 2

My tools are old:
Buildroot: Daily snapshot of 20060906:
My gcc: 3.4.6
Busybox: 1.2.0

I am using kernel patched with linux-feroceon_2_2_2_NAS_GDP
patch from marvell.
It does not compile with GCC 4.1.2 or later.

Kernel debugging also does not compile
(include/asm-arm/mach-feroceon/debug-macro.S is unavaliable).

The output with Gcc 3.4.6 compiled with is still same:

Please help me out of this problem if possible.
Thanks very much for kind attention.
