This forces everything to be regenerated by marking makesyscalls.lua as .PHONY, which may be helpful in, e.g., rebase scenarios, which may have unexpected effects on mtimes but still really need a regen. For now we apply this to the default sysent target, which is ran manually and not as a part of buildkernel. We can reconsider this if someone manually running it has issues with the runtime, but the top level sysent target can run each in parallel; I recommend -j4 or so.
