Introduce kern.opts.mk to hold all the options for kernel module builds. Include this in the right places. Make src.opts.mk optional so that modules can be built outside of the tree in the ports system. PR: 189520

# $FreeBSD$
# Options set in the build system that affect the kernel somehow.
#
# Define MK_* variables (which are either "yes" or "no") for users
# to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the
# make(1) environment.
# These should be tested with `== "no"' or `!= "no"' in makefiles.
# The NO_* variables should only be set by makefiles for variables
# that haven't been converted over.

Remove dependence on source tree options. Move all kernel module options into kern.opts.mk and change all the places where we use src.opts.mk to pull in the options. Conditionally define SYSDIR and use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all instances of CURDIR/../../etc with STSDIR, but only in the affected files. As a special compatibility hack, include bsd.owm.mk at the top of kern.opts.mk to allow the bare build of sys/modules to work on older systems. If the defaults ever change between 9.x, 10.x and current for these options, however, you'll wind up with the host OS' defaults rather than the -current defaults. This hack will be removed when we no longer need to support this build scenario. Reviewed by: jhb Differential Revision: https://phabric.freebsd.org/D529

# Note: bsd.own.mk must be included before the rest of kern.opts.mk to make
# building on 10.x and earlier work. This should be removed when that's no
# longer supported since it confounds the defaults (since it uses the host's
# notion of defaults rather than what's default in current when building

Add a FAST_DEPEND option, off by default, which speeds up the build significantly. This speeds up buildworld by 16% on my system and buildkernel by 35%. Rather than calling mkdep(1), which is just a wrapper around 'cc -E', use the modern -MD -MT -MF flags to gather and generate dependencies during compilation. This flag was introduced in GCC "a long time ago", in GCC 3.0, and is also supported by Clang. (It appears that ICC also supports this but I do not have access to test it). This avoids running the preprocessor *twice* for every build, in both 'make depend' and 'make all'. This is especially noticeable when using ccache since it does not cache preprocessor results from mkdep(1) / 'cc -E', but still speeds up compilation with the -MD flags. For 'make depend' a tree-walk is still done to ensure that all DPSRCS are generated when expected, and that beforedepend/afterdepend and _EXTRADEPEND are all still respected. In time this may change but for now I've been conservative. The time for a tree-walk with -j combined with SUBDIR_PARALLEL is not significant. For example, it takes about 9 seconds with -j15 to walk all of src/ for 'make depend' now on my system. A .depend file is still generated with the various rules that apply to the final target, or custom rules. Otherwise there are now per-built-object-file .depend files, such as .depend.filename.o. These are included directly by make rather than populating .depend with a loop and .depend lines, which only added overhead to the now almost-NOP 'make depend' phase. Before this I experimented with having mkdep(1) called in parallel per-file. While this improved the kernel and lib/libc 'make depend' phase, it resulted in slower build times overall. The -M flags are removed from CFLAGS when linking since they have no effect. Enabling this by default, for src or out-of-src, can be done once more testing has been done, such as a ports exp-run, and with more compilers. The system I used for testing was: WITNESS Build options: -j20 WITH_LLDB=yes WITH_DEBUG_FILES=yes WITH_FAST_DEPEND=yes DISK: ZFS 3-way mirror with very slow disks using SSD l2arc/log.

# Some options are totally broken on some architectures. We disable

# must change this code.
Add a note of clarification. MK_* variables only control what modules are built by default. You can still override that with MODULES_EXTRA for experimental features like ZFS and dtrace on some architectures. Also note that kernel config files are not affected by MK_ options listed, though some targets might be.

This would be useful for specifying features that are always broken or that cannot make sense on a specific architecture, like ACPI on pc98 or EISA on !i386 (!x86 usage of EISA is broken and there's no supported hardware that could have it in any event).
