When using a per-target compilation flag, Automake will choose a
different name for the intermediate object files. Ordinarily a
file like `sample.c' will be compiled to produce `sample.o'.
However, if the program's `_CFLAGS' variable is set, then the
object file will be named, for instance, `maude-sample.o'. (See
also *note Renamed Objects::.)
