This is not going to work, because set_icecc_env gets prepended anyhow,
so i just got the same error.

In fact, the icecc.bbclass declares:

do_compile_prepend() {
    set_icecc_env
}

and only in set_icecc_env the blacklist controls is performed.

The problem seems to be that do_compile in psplash_git.bb is written in python:

python do_compile () {
    import shutil, commands
    ....
}

so prepending just mixes the two languages.

Could be this the first case of mixing languages? Is bitbake able to
make some transformation when prepending/appending like that.

Also a some sort of conditional prepending based on languages could
works. What do you think?
