Makefile not work with the last SGDK

[kentosama]

Hi! A lot of things have been changed in SGDK and the makefile. I tried to adapt the Makefile that came with SGDK NIX, but I failed to compile a project. For now, here are the compilation errors:

I modified the Makefile of the lib in this way based on the latest version of SGDK, it is surely wrong.

Can you update the Makefile? Would be very appreciable 👍

Hi, I took the time to modify the two makefiles and it works great.

I allowed myself to align the size of the ROM and thanks to the SIZEBND tool.
