When building with the latest source that the wireguard importer script
fetches (http://WireGuard-0.0.20181218.zip) I am getting this error:

  AS      net/wireguard/crypto/zinc/chacha20/chacha20-arm64.o
fixdep: error opening config file:
../../../../../../kernel/google/marlin/net/wireguard/crypto/zinc/chacha20/chacha20-arm64.S:
No such file or directory
make[3]: ***
[/media/otherhd/benzorom/kernel/google/marlin/scripts/Makefile.build:301:
net/wireguard/crypto/zinc/chacha20/chacha20-arm64.o] Error 2

I'm assuming that it's trying to go to the wrong path with ../ but I can't
figure it out and so I don't know where to look in the wireguard source. I
can remove the importer script and go back to an old version (ex
http://WireGuard-0.0.20181119.zip) and all is well.

Any help would be appreciated.
