The inclusion of .MAKE.DEPENDFILE (.depend) has special logic in make to ignore stale/missing dependencies. bmake 20160220 added a '.dinclude' directive that uses the special logic for .depend when including the file. This fixes a build error when a file is moved or deleted that exists in a .depend.OBJ file. This happened in r292782 when sha512c.c "moved" and an incremental build of lib/libmd would fail with: make: don't know how to make /usr/src/lib/libcrypt/../libmd/sha512c.c. Stop Now this will just be seen as a stale dependency and cause a rebuild: make: /usr/obj/usr/src/lib/libmd/.depend.sha512c.o, 13: ignoring stale .depend for /usr/src/lib/libcrypt/../libmd/sha512c.c --- sha512c.o --- ... This rebuild will only be done once since the .depend.sha512c.o will be updated on the build with the -MF flags. This also removes -MP being passed for the .depend.OBJ generation (which would create fake targets for system headers) since the logic is no longer needed to protect from missing files.
