I know it's not possible to check it from recipe, but it might be useful
to mention which kernel options this requires, one of my builds failed
with:

wireguard-module/0.0.20170409-r0/WireGuard-0.0.20170409/src/Kbuild:30:
*** "WireGuard requires CONFIG_NETFILTER_XT_MATCH_HASHLIMIT to be
configured in your kernel. See
https://www.wireguard.io/install/#kernel-requirements for more info".
Stop.

So the error message is quite good, but still might be useful to mention
this URL in the recipe as well.
