pahole's processes DWARF -> BTF in a pseudo-random order if multi threading is enabled (default in the Linux kernel). This can be fixed in dependent derivation by making sure users don't ever pass "-j" or "-j N", but it seems easier and safer to just detect whether reprodubility is desired (by proxy: if SOURCE_DATE_EPOCH is set) and ignore the multi-threading flag.
