linux - Make cannot find present cross compiler -

i'm using make file compile kernel arm/xilinx platform.

i'm setting env variable cross_compile make file use.

i'm trying use cross compiler, present on system, called arm-xilinx-linux-gnueabi-gcc setting env var in following ways;

export cross_compile=/opt/xilinx/sdk/2015.2/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-  export cross_compile=arm-xilinx-linux-gnueabi- 

the make file should append gcc.

the error given both is

make: /opt/xilinx/sdk/2015.2/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gcc: command not found scripts/kconfig/conf --silentoldconfig kconfig make: /opt/xilinx/sdk/2015.2/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gcc: command not found   chk     include/config/kernel.release   chk     include/generated/uapi/linux/version.h   chk     include/generated/utsrelease.h make[1]: `include/generated/mach-types.h' date.   cc      kernel/bounds.s /bin/sh: 1: /opt/xilinx/sdk/2015.2/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gcc: not found make[1]: *** [kernel/bounds.s] error 127 make: *** [prepare0] error 2 

it works other arm cross compilers one.

why this?

according answers gave in comments, trying run 32bits executable on 64bits host platform.

so, if on ubuntu check this answer askubuntu.
