    mkelfimage: Fix build on x86_64 with hardening
    
    We get linking errors on some hosts like
    | ld -static --warn-multiple-gp --warn-common -T linux-i386/convert.lds -o objdir/linux-i386/convert ob
    jdir/linux-i386/head.o objdir/linux-i386/convert_params.o
    | objdir/linux-i386/convert_params.o: In function `printf':
    | convert_params.c:(.text+0x1fd): undefined reference to `__stack_chk_fail_local'
    
    This is because the build system is defaulting to host linker when building
    32bit binaries and it may not have same defaults as OE toolchain and issue
    gets highlighted.
    
    fix it by using cross linker for 32bit links when building on x86_64
