Seems to be no problem, as /usr/src/Makefile states this
as the default order:

For individuals wanting to upgrade their sources (even if only a
delta of a few days):

 1.  `cd /usr/src'       (or to the directory containing your source tree).
 2.  `make buildworld'
 3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
 4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
      [steps 3. & 4. can be combined by using the "kernel" target]
 5.  `reboot'        (in single user mode: boot -s from the loader prompt).
 6.  `mergemaster -p'
 7.  `make installworld'
 8.  `make delete-old'
 9.  `mergemaster'                         (you may wish to use -U or -ai).
10.  `reboot'
11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)

No, buildkernel, as all build activities, can be safely
performed in multi-user mode. There are just restrictions
in when to actually INSTALL built stuff. The kernel can
be installed in multi-user mode (but should be okay in
single-user mode, too), THEN the reboot into that new
kernel is performed, in single-user mode of course, and
finally the world is installed in this "construction
environment". After that, the system is rebooted again
to start into multi-user mode again with the fully
updated system (kernel AND world).
