* Added newlib changes
* Add action to launch PPSSPP simulator
* Remove legacy config for the stack and heap
* Add pthread
* Simplify kernel_functions and improve references to HAVE_KERNEL_PRX
* Add some flags
* Improve audio init/deinit
* Improve exit by clicking home
* Add CI for PSP1
* Update PSP.yml
* Fix old osx condition
Current code assumes that osx < 10.12 is equivalent to ppc osx. It's not
true as Leopard x86 is still < 10.12 but not ppc. As xcode compiles fat
binaries it includes osx x86 and compilation fails.
* Disable crtswitchres when no c++11 is available
Crtswitchres altually needs c++11. Since it's not that important to make
it compatible with lower c++, just disable if no c++11 is available
* Don't use firstObject on old Mac OS X.
It was introduced in 10.6, so on old ones just implement it ourselves
* Compile osx-ppc frontend
* osx-ppc: Build a fat binary
On 10.6 i386 xcode apparently refuses to build a pure ppc.
Settle for a fat binary.
Previously we would wait on the condition variable even in the non-blocking case.
This improves fast-forward performance massively and brings JACK in line
with other backends in that regard.
