[PATCH v9 4/6] kbuild: Support a FIT_EXTRA_ARGS environment variable

[Simon Glass]

In some cases it is useful to be able to pass additional flags to the
make_fit.py script. For example, since ramdisks are typically large,
passing -E to use external data can be helpful.

Add a new FIT_EXTRA_ARGS variable for this.
