Im having an error building "libretro/mame2016-libretro" on the Vero4k (aarch64) which has failed on the main repo and also "https://github.com/MrLightgun/mame2016-libretro" at the same stage:

Could not successfully build lr-mame2016 - MAME emulator - MAME 0.174 port for libretro (/home/osmc/retrOSMCmk2/submodule/RetroPie-Setup/tmp/build/lr-mame2016/mamearcade2016_libretro.so not found).`
I tried adding "PTR64 = 1" to makefile.libreto and makefile but it didnt seem to have any impact.
