I am not familiar with ecl, nor with its configury,
although the problem seems to be with its configury
itself. Checking for a size with knowledge that it
cannot while cross-compiling should be an oversight
in that software's configuration system. Updating it
to use newer autoconf would help, I guess, but
other developers here may have more to say on
that.
