Currently we construct the AUDIT_ARCH variable in the Makefile, then pass it into the C code with -D. The only place that uses it, though is the BPF filter generated by seccomp.sh. seccomp.sh already needs to do things differently depending on the arch, so it might as well just insert the expanded AUDIT_ARCH directly into the generated code, rather than using a #define. Arguably this is better, even, since it ensures more locally that the arch the BPF checks for matches the arch seccomp.sh built the filter for.

# definitely intended for web browser consumption. It should probably work the

# JavaScript portions to a plain Markdown, instead. However, cgit needs to use

# a file in the git tree. Find a better way around this.
