Depends on what you're trying to do.

These last two are completely and totally unnecessary for mceusb, even
in classic lirc mode. CONFIG_LIRC and CONFIG_IR_LIRC_CODEC handle all
of that, the last two are only to build lirc_foo device-specific drivers,
for things like lirc_serial. And CONFIG_IR_ENE is for a LPC integrated
IR receiver device (PNP id ENE0100 and friends), it has nothing to do
with mceusb. The various _DECODER bits aren't needed either if you're
doing decode in userspace with lircd.

That's a gentoo thing. Binary distributions build lirc with support for
all possible device types.
