That's indeed the LTCONFIG_VERSION which is not defined (see README). I
could have defined this in the ./build-it script but on the other hand when
you do a 'make' in builddir-cross directory you need this defined as well
outside './build-it' so you better have this defined in your shell
environment.

Perhaps we can add a check in './build-it' on LTCONFIG_VERSION being
"1.4a-GCC3.0" and if not error out (as it will result in a failed build
anyway) ?
