Thanks for reporting this issue! There has been some recent work in
this area by Leo:
https://lore.kernel.org/lkml/20251006-perf_build_android_ndk-v3-0-4305590795b2@arm.com/
The patches are in Linux v6.18-rc1. Perhaps you could try repeating
your build with this tree and reporting issues?

Thanks,
Ian
