I found the type of problem --but it is not a obvious extension of
the prior material: META_MODE recorded something that indicates the
actual problem . . .

/usr/obj/BUILDs/main-CA76-nodbg-clang/usr/main-src/arm64.aarch64/lib/libpmc/pmu-events/jevents.pieo.meta:R
12651 /usr/include/fts.h

The build is using the /usr/include/fts.h from the live old system
while trying to build the new system.

Given the FTSENT change of layout from old to new, that does not
work. Also, this is not something that clearing out /usr/obj/ . . .
and rebuilding fixes.

The build of lib/libpmc/pmu-events/jevents.* should get the fts.h
file from the source tree being built, in my case I was working in
/usr/main-src/ so:

# find -s /usr/main-src/ -name fts.h -print
/usr/main-src/include/fts.h

lists a path to the file that should have been used for the build.

I expect that this would be a libpmc development issue, not a fts
development issue for who solves it.


Also: this turns out to not be an arm specific problem.
