[DragonFlyBSD - Bug #3347] pctrack fails with kvm_nlist: No such file or directory

[sigttou]

Issue #3347 has been updated by sigttou.

File 0001-pctrack-debug-pctrack-message.patch added

`pctrack` needs `_ncpus`, `_cputime_pcheader` and `_cputime_pctrack`, which only exist with `DEBUG_PCTRACK`. When they are missing, `kvm_nlist` fails and the tool prints the unrelated "No such file or directory". The patch checks whether the symbols resolved and, if not, tells the user to rebuild the kernel with `options DEBUG_PCTRACK`. Otherwise the previous error path is kept.
