0-byte model files no longer crash the game; Linux build cleanups
Commit 038c27 on main handles 0-byte model files that were crashing the game; commit 75a5a6 gets Linux32 building again for now.
- 038c27: unused Bootil features that print warnings disabled; less Linux compile log noise; unused libraries removed from
lib/; 0-byte model files handled; compile warning fixes; Linux64 build progress; tool projects renamed internally - 75a5a6: "Get Linux32 to build for now. Seems there's a VPC bug on Linux that needs investigating"
