Start with the macremapper package build files and the kernelmod build invocation shown in the report, including kernelmod/main.c and patches/01_fix_nf_hooks.patch. Reproduce the build on the affected powerpc and aarch64 OpenWrt targets with ASLR PIE enabled, then verify that the macremapper kernel module builds successfully.
