OK, so this is an additional (second) test run for a special
configuration, but the code to perform the test has just been
duplicated from the top level makefile (which is not a nice thing).

I think we should tun this code either into a Makefile function that
is defined only once and can then be used elsewhere as well, or
turn it into an external script unter scripts/

What do you think?

What is your exact build target / command sequence to get here?

The "limit:  0 bytes" clearly indicates that the definition of
CONFIG_BOARD_SIZE_LIMIT is not known to Make at this point, or
wrong.

In the meantime, having the patch applied both to the TL Makefile
and to the imx one should work at least as good as the previous
code.

If I know how to repeat your exact test, I can try to fix that.
