Some flags do nothing but generate dozens of warnings later,

Main culprit is '-fvisibility-inlines-hidden' which is invalid for C files
Disable by default, to be used by distributions who care to try and
prefer system-wide libraries when available. It makes sense for us to
keep using vendored libs by default when possible to make it easier for

figure out which dependencies they can share with the rest of the
system.
BundleUtilities uses `ABSOLUTE`, and if you use `REALPATH` (which removes symlinks) and compile from a path that contains symlinks, BundleUtilities will complain about things not being inside the main app bundle because some paths don't match
Allows us to bring includes and relevant libraries into scope by explicitly declaring linkage against the target
as opposed to using a variable. Also removes the dumping of OProfile includes into the top-level directory.
Use @Orphis's FindFFmpeg module from ppsspp:

From that commit:

The latest version has tons of security fixes (which is expected for a
library such as mbedtls).
Updating also allows getting rid of a few deprecation warnings.
