+Subject: [PATCH] MINOR: tools: use public interface for FreeBSD
+ get_exec_path()
+
+Where possible (FreeBSD 13+), use the public, documented interface to
+the ELF auxiliary argument vector: elf_aux_info().
+
+__elf_aux_vector is a private interface exported so that the runtime
+linker can set its value during process startup and not intended for
+public consumption.  In FreeBSD 15 it has been removed from libc and
+moved to libsys.
