Hello All,

I am trying to compile the linux 2.6.36 kernel for arm-linux. This is
the error I am getting during compilation.

clfs at prasad-desktop:/mnt/clfs/sources/linux-2.6.36$ make
ARCH=${CLFS_ARCH} CROSS_COMPILE=${CLFS_TARGET}- zImage modules
CHK include/linux/version.h
CHK include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
CC kernel/bounds.s
kernel/bounds.c:1:0: error: FPA is unsupported in the AAPCS
make[1]: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2

These are the environment variables
export BUILD="-mabi=arm-linux"
