Don't include bsd.own.mk from sys.mk, this makes it impossible to use ``.if defined()'' inside bsd.own.mk to test for defines in individual makefiles. For example, setting DEBUG_FLAGS in Makefile didn't take the desired effect on the STRIP assignment. Added bsd.init.mk (like in NetBSD) that handles the inclusion of ../Makefile.inc and bsd.own.mk from all bsd.*.mk files that "build something". Back out bsd.own.mk,v 1.15: moved OBJFORMAT initialization back to sys.mk (several source tree makefiles want to check it early) and removed MACHINE_ARCH initialization (it's hard to see from looking at the commitlogs what the problem was at the time, but now it serves no purpose). Prohibit the direct inclusion of bsd.man.mk and bsd.libnames.mk. Protect bsd.obj.mk from repetitive inclusion. Prohibiting the direct inclusion of bsd.obj.mk might be a good idea too.

Add META_MODE support. Off by default, build behaves normally. WITH_META_MODE we get auto objdir creation, the ability to start build from anywhere in the tree. Still need to add real targets under targets/ to build packages. Differential Revision: D2796 Reviewed by: brooks imp

AUTO_OBJ: Set .OBJDIR=.CURDIR earlier for NO_OBJ Makefiles. auto.obj.mk is loaded before the Makefile which may have NO_OBJ set inside of it. In that case we can't avoid creating the OBJDIR but we do need to avoid using it. Fixing .OBJDIR in bsd.init.mk at least fixes all of the build .mk files to have a proper .OBJDIR. It does not fix the Makefile itself but usually if they have NO_OBJ set they are not inspecting ${.OBJDIR} anyhow. It is ideal to only have this in bsd.init.mk and to remove it from bsd.obj.mk, but then bsd.obj.mk would need to include bsd.init.mk. Doing something like that would require more testing. It has been proposed that bsd.obj.mk not be included directly but it has been possible for too long to do so to change it at this point. Note too that it may make sense to fix .OBJDIR even when AUTO_OBJ is not enabled but the historical behavior has always been that NO_OBJ just avoids running 'make obj', so .OBJDIR should already be .CURDIR. Also while NO_OBJ seems like it should be removed at this point, it is not always possible to fix Makefiles to properly use an .OBJDIR. The cost of keeping NO_OBJ support is minimal.

Handle some .OBJDIR == .CURDIR cases. - If OBJROOT is SRCTOP then don't add on TARGET.TARGET_ARCH. This only happens at the top-level, and for sub-directories when the user is clever with MAKEOBJDIRPREFIX=/. - Don't bother checking 'test -w' on .CURDIR. - Properly set OBJTOP/OBJROOT to SRCTOP in various needed cases. - Check if the OBJDIR is writable even for *clean* targets since it determines which .OBJDIR the user gets; If they cannot write to an existing eligible .OBJDIR then it needs to clean in .CURDIR instead. - Add guard to cleanworld/cleanuniverse from removing SRCTOP. - Ensure OBJTOP is proper for .OBJDIR=.CURDIR which fixes finding libraries since src.libnames.mk is based on OBJTOP. - Avoid some chdir(2) for modifying .OBJDIR Sponsored by: Dell EMC Isilon

Use OBJS_SRCS_FILTER to control setting OBJS from SRCS Some makefiles do reachover builds. In some cases it is convenient to list subdirs of the distribution in SRCS. It is not very convenient, or always even desirable to have corresponding subdirs in .OBJDIR, so OBJS_SRCS_FILTER allows the makefile to choose. The default value 'R' matches existing practice. But a makefile can set OBJS_SRCS_FILTER= T (the R gets added by bsd.init.mk) to avoid the need for subdirs in .OBJDIR Differential Revision: https://reviews.freebsd.org/D12218 Reviewed by: bdrewery

Fix INSTALL_AS_USER with external nsswitch databases The INSTALL_AS_USER option tells "install" to use the current user name as the owner of the installed file. The "install" command executed by the build is statically linked, so it does not load nsswitch modules, such as nss_ldap.so, so it fails when the user is only defined in such a database. Fix it to use the current UID instead of user name. This works for all users. I expect it is also slightly more efficient.
