289466 by andrew:
Replace build_section_pagetable with build_l1_block_pagetable as it takes
an extra argument to specify the number of 1GiB pages to map. This should
be a nop as we are only mapping a single page, but when we move to use an
extra level of page tables we will be able to map a second block, e.g. if
the kernel was loaded over a 1GiB boundary.

Only use -fstack-protector-strong with supported compilers

This includes clang 3.5.0+, gcc 4.2.1, gcc 4.8.4+

This allows me to do subdirectory makes again after setting
MAKESYSPATH on 10.2-RELEASE as it comes with clang 3.4.1.

As a sidenote: this isn't technically correct for all vintages
of gcc 4.2.1, but will be correct when gcc is rebuilt/reinstalled
after r286074, so this version check should be good enough.

Fix wrong PATH being set for world 'includes' stage after r289438.

The 'includes' target is currently a pseudo target in that
does 'cd ${.CURDIR} && ${MAKE} buildincludes && ${MAKE} installincludes',
versus all over targets that just recurse.

In Makefile.inc1 the older duplicated logic for calling
'includes' was being executed in each subdir directly, meaning 'cd lib && make
includes' became 'cd lib && make buildincludes && make installincludes'.  Now
that the logic is used it is calling 'make buildincludes && make
installincludes' from the top-level which pulls in the PATH=<default path>
from /Makefile.

The sub-make logic for 'includes' in was attempted to be removed
in r289282 but turned out to be wrong.  I have a working version now but
it is not yet ready for commit.  So for now in Makefile.inc1 split out
'includes' to 'buildincludes' and 'installincludes' which will avoid the

Rework the 'make -n -n' feature such that '-n' recurses and '-N' does not.

Bmake has a documented feature of '-N' to skip executing commands which is
specifically intended for debugging top-level builds and not recursing into
sub-directories.  This matches the older 'make -n' behavior we added which made
'-n -n' the recursing target and '-n' a non-recursing target.

Removing the '-n -n' feature allows the build to work as documented in
the bmake manpage with '-n' and '-N'.  The older '-n -n' feature was also
not documented anywhere that I could see.

Note that the ${_+_} var is still needed as currently bmake incorrectly
executes '+' commands when '-N' is specified.

The '-n' and '-n -n' features were broken for several reasons prior to this.
r251748 made '_+_' never expand with '-n -n' which resulted in many
sub-directories not being visited until fixed 2 years later in r288391, and
many targets were given .MAKE over the past few years which resulted in
non-sub-make commands, such as rm and ln and mtree, to be executed.

This should also allow removing some indirection hacks in and
other cases of .USE that have a .MAKE by using '+'.

Conditionalize the META_MODE tool handling on MK_META_MODE.

It was not being used outside of META_MODE but this should make it more clear
that it is only for META_MODE.
