You may find it helpful to do something like:
make -dv -C sys/modules/vmm -V CFLAGS > /tmp/dvo 2>&1
egrep ':.PARSE|/usr/src/sys' /tmp/dvo | grep -B1 usr/src | more
The arg to -V doesn't matter btw.
You could narrow that down if you know what var -I/usr/src/sys is in
(probably CFLAGS but you never know)
the above should help find the makefile that is introducing the bogus -I
Thank you, that does help narrow it down: (I backed up a vew lines
from the first place I saw src/.)

Oh my! Uggggg
So something in bsd.kmod.mk is going very wrong... it looks like it
starts to pull all sorts of stuff from /usr/src/sys!
I seem to remember that there is code in the Makefiles that looks for
the sys directory.
I believe it can be directed to use a directory but in its absence it
looks at some well
known locations, which would probably fail if there is already a
DIFFERENT tree in /usr/src.
I have wrapped the long line so I can point to a difference between
r329294 and r332262 make log of this file.
r329294 make output:
cc -O2 -pipe -DVMM_KEEP_STATS -DSMP -fno-strict-aliasing -Werror -D_KERNEL \
-DKLD_MODULE -nostdinc -I/usr/src-topo/sys/amd64/vmm \
-I/usr/src-topo/sys/amd64/vmm/io -I/usr/src-topo/sys/amd64/vmm/intel \
-I/usr/src-topo/sys/amd64/vmm/amd -I. -I/usr/src-topo/sys -fno-common \
^^^^^^^^^^^^^^^^^ this is what I would
expect
