Make thinks it knows how to build this target, or that it's already
built.

Possible reasons are (a) that file does exist, maybe on VPATH, or (b)
you have a target "lpc.o" in your makefile with no rule or
prerequisites (see the section "Rules without Commands or Prerequisites"
in the GNU make manual).
