This is presumably just because there are additional changes that were
merged to stable/12 and not stable/11.
kevans' "MFC -fno-common fixes" commit is:
stable/11 e9ba4c1e146d1ebf889b73a78878807c8bc3f0cb
stable/12 9a042535a9eb5ea8dd1b3e0d80483d02f1cba951
as you mentioned this is the most recent usr.bin/systat commit in
stable/11, while there are three additional changes in stable/12 in
usr.bin/systat after that one. But if we compare usr.bin/systat at
those two hashes we see:
$ git diff --stat e9ba4c1e146d1ebf889b73a78878807c8bc3f0cb
9a042535a9eb5ea8dd1b3e0d80483d02f1cba951 usr.bin/systat
usr.bin/systat/Makefile | 2 +-
usr.bin/systat/Makefile.depend | 1 -
usr.bin/systat/cmds.c | 4 +++-

25 files changed, 234 insertions(+), 152 deletions(-)
So the failure from `git cherry-pick -x` is just a patch conflict, the
same as would occur trying to merge those three commits in SVN.
$ git cherry-pick -x a70af2507f720c2d7f56f51a18d358123b4770a5

As with svn you can edit the conflicting files and then commit the
result - or, cherry-pick the other changes that are missing from
stable/11 if appropriate.
It seems two files conflicted:
usr.bin/systat/vmstat.c
usr.bin/systat/zarc.c
the conflict in the former can be resolved automatically; for zarc.c
you can check what's merged to stable/12:
% git log ..freebsd/stable/12 usr.bin/systat/zarc.c
Looking through the commits it seems at least
45e9405ea4b05926b22a743237cbfe918206db50 was not merged and is
responsible for at least one of the conflicts.
