ru b48a558a6b Introduce DPSRCS, that holds the list of source files which are
needed for generating dependencies.  SRCS are always part of it,
and normally only they.

This can be useful in some random cases where it's necessary to
have something in .depend that isn't part of SRCS.  This will be
used to replace a hack in lib/libpam/libpam/Makefile.
