Thanks for the information.

The -dM output's "is newer than the target" lines
show the path from before the above transformation.
(The :tA results possibly could use another
sort/uniq sequence for the realpath results?)
I've been pondering things because, so far, my
attempts to experiment with this has failed to make
the -dM output lines for the paths go away and it
still does the related build activity. I've been
trying the likes of:
.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 =
${OBJTOP}/tmp/legacy/usr/sbin/${ignore_legacy_tool}
.endfor
.for ignore_other_tool in ctfconvert objcopy nm
.MAKE.META.IGNORE_PATHS+=3D ${OBJTOP}/tmp/usr/bin/${ignore_other_tool}
.endfor
in what I use for make.conf via:
__MAKE_CONF=3D/usr/home/root/src.configs/make.conf
It is using paths that match the -dM output lines ( sbin
use despite sbin -> ../bin being a symbolic link).
Note: WORLDTMP is not defined that early, thus the ${OBJTOP}/tmp
use.
-V.MAKE.META.IGNORE_PATHS is showing the paths I would
expect, matching the -dM lines.
So I'm still pondering what might be going on.
