@PallHaraldsson this PR exposes the bpf_trace_printk helper (as BPFnative.RT.trace_printk), which you can use to print custom output to /sys/kernel/debug/tracing/trace. Check the "helpers" testset in the root-only tests for examples of how to use this.

Also, in this PR I've disabled BTF output, since we're throwing assertions in LLVM during BTF generation. I'll probably need to finish maleadt/LLVM.jl#152 so we can fixup our debuginfo to match what LLVM (and the kernel) expects.
