It depends whether the `gpm` USE-flag is set or not. From the ncurses ebuild:
(See [1] for documentation regarding the ${MULTILIB_USEDEP} eclass variable.)
DEPEND="gpm? ( sys-libs/gpm[${MULTILIB_USEDEP}] )" [2]
The list of architectures you're seeing is an expansion of ${MULTILIB_USEDEP}
as defined by the `multilib-build` (or in this case, `multilib-minimal` eclass);
this can be removed from the output by passing the local option -U to depgraph.
As all of these are disabled, I'm guessing you're not running a multi-lib
profile.

What do you mean, "but it's *--*" ? Do you mean it's disabled ? Equery lists
dependencies as specified by the DEPEND ebuild variable, regardless of your own
system's USE-flags. Try running the same equery command for something with lots
of optional dependencies, such as Firefox, and you'll see the same behaviour.
