Those of you that use the uClinux elf2flt toolchain will find that
__stack_start is not correctly defined.  This is due to a bug in the elf2flt.ld
linker script.  Edit either/both elf2flt.ld (from a binary distribution) or
elf2flt.ld.in (from the source distribution) to output the .stack section to
the flatmem memory image:

From

    .stack : {
        . = ALIGN(0x4);
        __stack_start = .;
    }

To

    .stack : {
        . = ALIGN(0x4);
        __stack_start = .;
    } > flatmem
