Seems in case of 32-bit library, usage of msse2 makes
some stack corruption or incorrect instructions.
Usage with mstackrealign fixes that case.

Hey Sergii,

Thanks a lot for looking into this issue.
I think you might need to update the other build systems (Android.mk/meson).

The toplevel meson/makefile have a -mstackrealign that seem to make the description of the issue you're fixing.
Maybe that's where this change should go.

Thanks,
