Also fix up libbizhash so it builds on clang
Slight fixes to sameboy and msxhawk makefiles
Fix rcheevo submodule commit (no actual changes, just make it point to a commit upstream actually has)
SDL2 .so not yet rebuilt, need to consider how to do that
citra seems to need at least Debian 11 to build
libe_sqlite3.so seemed to have already been built with Debian 10 so not bothering touching that
libwaterboxhost.so is Rust / targets glibc 2.28 anyways, nothing needs to be done there
