You get this fix if you run -current after a given point, and if
you run recent netbsd-9, via this CHANGES-9.1 entry:

lib/libc/gen/pthread_atfork.c                   1.13,1.14
libexec/ld.elf_so/rtld.c                        1.204,1.205
libexec/ld.elf_so/rtld.h                        1.139,1.140
libexec/ld.elf_so/symbols.map                   1.3,1.4

        Introduce intermediate locking for fork, so that the  dynamic
        linker is in a consistent state.
        [chs, ticket #907]

And in my case my armv7 system has this fix in its ld.elf_so:

armv7: {8} ident /usr/libexec/ld.elf_so | grep rtld.c
     $NetBSD: rtld.c,v 1.197.2.4 2020/05/13 18:08:38 martin Exp $

and I did the build with the MAKE_JOBS_SAFE=no commented out in
rust's Makefile, and it used all 4 (virtual) CPUs during the
build.
