It's required to fix missing defines building for opengles2 (videocore) as with v1.16.6 of ppsspp.
Use the __mod_info array to get the path of the patch, so it works when called from the lr-ppsspp scriptmodule.
Core on v1.13.2 fails to run on Pi4 with the error:
...
[ERROR] Failed to open libretro core: "/opt/retropie/libretrocores/lr-ppsspp/ppsspp_libretro.so"
Error(s): /opt/retropie/libretrocores/lr-ppsspp/ppsspp_libretro.so: undefined symbol: hostAttemptBlockSize
This was fixed upstream with commits 1cd34f9d2bef6c92ed457c6aa85bf4d9b5111e90 and 7c5d36eca76c905a122c1, which are combined in the .diff file in this commit.
GL_COMPRESSED_RGBA_ASTC_4x4_KHR isn't available in the videocore iv gles2 includes, and documentation suggests this is an opengles 3 extension.
Add ifdefs to not include this if it isn't defined.
The 'ubershaders' introduced in v1.14 are not handled efficiently by the Mesa v3d driver, causing a performance regression [1].
Since the slowdown is not present in the Mesa version from Bullseye/Bookworm (which caused in part the version upgrade), install v1.13.2 just on Buster/RPI.

Both stand-alone `ppsspp` and the libretro core `lr-ppsspp` share the `$HOME/.config/ppsspp` save file directory.
`moveConfigDir` removes the symlink on removal; this will disconnects the existing saves from the remaining emulator.
ppsspp: Use moveConfigDir only on install.
On removal, do not use the helper function. Remove the symlink manually and only if no remaining PSP emulators.
lr-ppsspp: Libretro core did not link this dir at all, and just used mkUserDir instead. Switch to use moveConfigDir and same fix as above, for libretro core also.
Current master has shader issues on videocore causing a black screen, so switching back to last tagged version - v1.12.3.
Historically we have had to fix up a fair number of ppsspp issues on the RPI due to upstream changes so sticking to a stable release seems like a good idea and allows us to test before we update.
The PPSSPP repository is also quite active and re-building ppsspp/lr-ppsspp binaries for every change takes a lot of time, so this also frees up some cpu time on our build system.
PPSSPP CMakeLists.txt adds -latomic for android targets, but this is also needed on armv6 on RaspberryPi OS Buster.
This commit sets the variable ATOMIC_LIB to "atomic" for videocore / armv6 so that -latomic is added.
Users reported that this version runs faster on videocore on the rpi1/2/3
Adjusted ppsspp sources to allow branch parameter and fixed build subfolder to ppsspp
so that paths are the same for md_ret_files, including adjusting lr-ppsspp in the same way.
Older code builds ok with our current ppsspp module script on rpi1/2/3 + videocore gles2,
but not rpi4, which it isn't needed on anyway. This may need changing if we have to update
ppsspp further in the future.
upstream are now doing a check for rpi model based on sysfs file which breaks when building
in a chroot or on other non rpi hardware (but targetting the rpi)
CMakeLists.txt uses CMAKE_SYSTEM_PROCESSOR and adjusts flags based on this
however if building on rpi2/3 or in a chroot with __platform=rpi1 this will
still return armv7l as it uses "uname". This causes armv7/neon code to be included
which causes building to fail. We can override this by setting -DFORCED_CPU=armv6
which fixes building for the rpi1
* change existing calls which used --strip-components
* use multiple parameters for arguments which should allow additional arguments with spaces
* implements #2630
Changes for all builds:
* Use the master branch (v1.6.3 is missing important EGL fixes)
* Disable Vulkan on non-X11 ARM targets to prevent build error
* Default to fullscreen on non-X11 targets
* replace many of the existing wget | tar commands with the new function
* include error logging in the function via runCmd, to trap download/unpacking issues
