maybe: @httpstorm can help with this one. :-)

Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start with the luajit2 build in the package repository and the src/Makefile rule reported at line 695. Reproduce the cross-build on macOS, trace the pointer-size mismatch, and verify that luajit2 builds successfully for the mvebu/cortex-a9 target.
