I haven't seen any issues related to the introduction of savedcmd_; and
roughly searching through tools/ I cannot find a rule that matches the
pattern Masahiro described in commit 92215e7a801d ("kbuild: rename
cmd_$@ to savedcmd_$@ in *.cmd files", 2022-12-29). For consistency,
I'd like to see the build rules in tools/ re-use the ones from scripts/
but as of now I don't see any necessity to introduce savedcmd in
tools/, yet.

Kind regards,
Nicolas
