All paths that I'm adding are absolute paths.
For reference (my additions are after the normal

other substitutions vs. not):

The contribution to the list is currently generated via
use of:
.if ${.MAKE.LEVEL} =3D=3D 0
.for ignore_legacy_tool in awk cap_mkdb cat cp crunchgen crunchide dd =
egrep env file2c gencat grep gzip jot lex lb ln m4 mkcsmapper mktemp mv =
patch realpath rm sed sh touch truncate uudecode uuencode xargs
.MAKE.META.IGNORE_PATHS+=3D =
${MAKEOBJDIR}/tmp/legacy/usr/sbin/${ignore_legacy_tool}
.endfor
.for ignore_other_tool in ctfconvert objcopy nm
.MAKE.META.IGNORE_PATHS+=3D =
${MAKEOBJDIR}/tmp/usr/bin/${ignore_other_tool}
.endfor
.MAKE.META.IGNORE_PATHS:=3D ${.MAKE.META.IGNORE_PATHS}
.endif
The :=3D use is how I avoided needing to worry about late binding
substitutions for my additions (independent of the internals of
make's specific .MAKE.META.IGNORE_PATHS handling).
