Patches for mednafen on Minerva

0001-Make-mednafen-compile-with-PIC-PIE.patch

Make mednafen compile with PIC/PIE

We currently don't support copy relocations and mednafen compiles with PIC/PIE disabled for performance reasons. This re-enables it and disables the compiler warning it emits for having it enabled.

0002-Replace-PTHREAD_MUTEX_ERRORCHECK-with-PTHREAD_MUTEX_.patch

Replace PTHREAD_MUTEX_ERRORCHECK with PTHREAD_MUTEX_NORMAL

We currently don't support the PTHREAD_MUTEX_ERRORCHECK mutex type.
