All paths that I'm adding are absolute paths.
For reference (my additions are after the normal
ones, I use -dV here to show what is based on
other substitutions vs. not):

The contribution to the list is currently generated via
use of:
.if ${.MAKE.LEVEL} == 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+= ${MAKEOBJDIR}/tmp/legacy/usr/sbin/${ignore_legacy_tool}
.endfor
.for ignore_other_tool in ctfconvert objcopy nm
.MAKE.META.IGNORE_PATHS+= ${MAKEOBJDIR}/tmp/usr/bin/${ignore_other_tool}
.endfor
.MAKE.META.IGNORE_PATHS:= ${.MAKE.META.IGNORE_PATHS}
.endif
The := 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).
