Error: Compiling src/emu/validity.cpp...

[henryjfry]

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:

I tried adding "PTR64 = 1" to makefile.libreto and makefile but it didnt seem to have any impact.
