Core cannot be built

[MiltosKoutsokeras]

System: Debian 10 x86_64
Source code: Commit as HEAD b68d72b
Steps to reproduce:

1. Checkout the code
2. Change dir into libretro-bsnes/bsnes
3. Invoke the make command: make -f GNUmakefile platform="unix" -j12 CC="gcc" CXX="g++" compiler="g++" target="libretro"
4. Nothing is produces in libretro-bsnes/bsnes/out, build process stops just under Compiling processor/wdc65816/wdc65816.cpp ...

Full output with make --debug:

make --debug -f GNUmakefile platform="unix" -j4 CC="gcc" CXX="g++" compiler="g++" target="libretro"
