Do we have a policy for QA regarding to whether USE_EXPAND flags should
also show up in IUSE?
Take, for example, a scenario like this:
RDEPEND="elibc_foo? ( foolibc )"
The metadata cache will generate the IUSE flag as empty as well,
breaking stuff like my little GPNL tool that needs to read it to see
what use flags are implemented.
Obviously, portage is fine without it in there, but I wanted to know
what our policy is. Plus, I'd like to fix them so that the IUSE is
correct as well.
