Is it safe to interrupt (Ctrl + C) while building a port or kernel?

That's fine, yes.  But I wouldn't do an unconditional installkernel
after buildkernel (suppose buildkernel failed in some way)?

Either include both targets in the same make command:

make buildkernel installkernel

Or make the second conditional on the outcome of the first:

make buildkernel && make installkernel

You might also save yourself some time by using "-DNO_CLEAN" after
changing your kernel config.
