Thanks!

The binary seems not to be the issue itself, it runs fine and does strange
things:

  1751   1751 current_exe_mism CALL  execve(0x7e2e41557040,0x7e2e41557080,0x7e2e41508000)
  1751   1751 current_exe_mism NAMI  "/usr/libexec/ld.elf_so"

and running /usr/libexec/ld.elf_so directly is not supported on NetBSD.
I guess it is some linuxism to get something simmilar to our ldd output
(the program previously runs readelf, maybe it is trying to compare output).

So nothing wrong with NetBSD AFAICT, but just a bogus test.
