optimized application for own computer

according to ChatGPT:
Removed -mssse3, -msse4.2, and -mpopcnt:

These flags are not needed when using -march or -mtune.
Both -march=native (if used) and -mtune=native automatically detect and enable relevant instruction sets based on the target CPU.

---

Kept -m32 for 32-bit builds (CFLAGS_x86):

This is required for explicitly targeting 32-bit systems.

---

Kept -march for architecture specification:

-march=i686 ensures compatibility with i686 systems for 32-bit builds.
-march=x86-64 ensures compatibility with 64-bit x86 systems.

Why -mtune=native Is Better in This Case

Using -mtune=native ensures that the generated code is tuned for the exact machine where it is compiled, potentially yielding better performance compared to the generic -mtune=intel. -------------

I DID NOT TEST THIS CODE!!!

This is not an appropriate thing to do, in general. This is for targeting android apps. -march=native will tune for your PC, not the PC you're targeting.

But, also, AFAIK, all x86 Android targets are Intel, so that's why I went with it.

Overall, this was largely to duplicate the default settings from what Android studio targets.
