cuckoo_miner not compiling on Raspberry Pi 3 Jessie/GCC 6.3

[photis]

Fur tracking purposes.

On a standard Raspberry Pi 3 (arch: armv7) where I "up-fitted" Jessie with GCC 6.3.0 (I can't use Stretch because of its wifi issues). Probable cause: hard-coded x86 compiler flags (-m64 -mavx2) in some build scripts.

Seems -m64 is not needed. Will take it out of my Makefile. Once Yeastplume updates this should no longer be a problem...
