At least on FreeBSD 5.x there is no need to build a customer kernel.
The following can be set in /boot/loader.conf

     # defaults for FreeBSD are as follows
     # SEMMNI=10, # of semaphore identifiers
     # SEMMNS=60, # of semaphores in system
     # SEMUME=10, max # of undo entries per process
     # SEMMNU=30, # of undo structures in system
     kern.ipc.semmni=40
     kern.ipc.semmns=240
     kern.ipc.semume=40
     kern.ipc.semmnu=120

these will be set on boot.
