Thanks Varka for your help!

It compiles now without those module:
- kmod-bluetooth
- kmod-bluetooth_6lowpan
- kmod-6lowpan
- kmod-ieee802154
- kmod-ieee802154-6lowpan
- kmod-ieee802154-drivers
- kmod-mac802154
- kmod-wpan-at86rf230
- wpan-tools

It's basically the same conf as yours.

I don't get why those module would make an error since they worked
well with Linux 3.18.

Here are my tries:
- kmod-6lowpan
- kmod-ieee802154
- kmod-ieee802154-6lowpan
- kmod-ieee802154-drivers
- kmod-mac802154
- kmod-wpan-at86rf230
- wpan-tools
--> ERROR: module
'/trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7628/linux-4.0.4/net/ieee802154/af_802154.ko'
is missing.
