This line would be redundant when you "make buildworld" -- in this
case, the fresh headers are used.
But if you are looking for a way to compile a program with a new
(previously non-existent) header, the above makes sense.
Alternatively, you can "make .. DEBUG_FLAGS=-I${.CURDIR}/.../sys"
without modifying the makefile.
