config / NOTES "profile 2" and main -> stable/13 fails universe for me?

I am building on a stable/13 machine (updated a few days ago but I had
that before in the last months).

I have git clone and am mostly working on main or main-derived

Once in a while I switch in-place (not a worktree) to a stable branch,
e.g., git checkout stable/13 based on freebsd/stable/13 for MFCs.

When I do that and start to build an amd64-only universe my kernel
builds immediately fail with a dubious error message from a top-level

# nice make -s -j30 tinderbox TARGETS=amd64 [..]

make[2]: ".../freebsd-src/Makefile" line 731: "Target architecture for amd64/conf/LINT unknown.  config(8) likely too old."

I tracked it down to the profile 2 line sys/amd64/conf/NOTES which makes
config fail apparently.

When I apply the below change things work flawlessly.

I do not fully understand where the problem comes from, but given I
haven't seen other reports I wonder what it is that I am doing that
makes things go wrong here?

Anyone an idea?

Lots of health,
