It shouldn't be a case of missing libs as i am able to build and run the
kernel from the same. I played around with the linker options

LDFLAGS= -nostdlib -L/opt/montavista/devkit/arm/v5t_le/target/usr/lib
-L/opt/montavista/devkit/arm/v5t_le/lib/gcc-lib/armv5tl-hardhat-linux/3.3.1 -L/opt/montavista/devkit/arm/v5t_le/armv5tl-hardhat-linux/lib

With this i am past the previous error and the new error is

/opt/montavista/devkit/arm/v5t_le/lib/gcc-lib/armv5tl-hardhat-linux/3.3.1/../../../../armv5tl-hardhat-linux/bin/ld: warning: cannot find entry symbol _start; defaulting to 00008074
/tmp/cc0VA6xr.o(.text+0x8): In function `main':
: undefined reference to `puts'
collect2: ld returned 1 exit status

I guess it's something to do with path but i'm not sure what exactly.

The code i'm trying to build is

#include<stdio.h>
int main (void)
{
printf("Hello World - arm linux\n");
return 0;
}
