sys/kern/imgact_elf.c
981 ↗	(On Diff #55566)	This block is irrelevant for the task of loading the interpreter. I must not be moved.

Rework a bit.

sys/kern/imgact_elf.c
961 ↗	(On Diff #55666)	This block of if() can be naturally moved before calculating newinterp.
971 ↗	(On Diff #55666)	How could newinterp != NULL and brand_info->interp_path == NULL ?

Reorder.

sys/kern/imgact_elf.c
971 ↗	(On Diff #55666)	The newinterp comes from brand_info->interp_newpath, not brand_info->interp_path.

More rework - goto is done, as is the 'newinterp' variable.

Looks fine, please test with 32bit binary.
