Fixed annoying non-null output for `make depend'.  SRCS should only be used for C, C++ and assembler sources if <bsd.prog.mk> is included.  It was used for general files.  This caused the __depend_* lists in <bsd.dep.mk> to be empty, so mkdep was never run, so .depend never existed, so it was always out of date, so `rm -f .depend' was always executed to update it.
