If we pre-process using `.d` files, post-processing only adds a little extra sanity, because the code shall not directly use `DTRACE_PROBE*` but dedicated macros, and thus misuses are caught at the compile time. Although the user can still use those generic macros, such usage can be checked with [syntax-check](https://git.savannah.gnu.org/cgit/gnulib.git/tree/top/maint.mk#n203) rules (i.e., no git-controlled files directly include `<sys/sdt.h>` and no `DTRACE_PROBE*` macros are invoked).
If we really care about the final ELF output, we can add something similar (but not in Perl, maybe good to talk to the libabigail developers first).
