In order to do so we need to install the msdosfs headers to the bootstrap
sysroot and avoid includes of kernel headers that may not exist on every
host (e.g. sys/lockmgr.h). This change should allow bootstrapping of makefs
on FreeBSD 11+ as well as Linux and macOS.
We also have to avoid using the IO_SYNC macro since that may not be
available. In makefs it is only used to switch between calling
bwrite() and bdwrite() which both call the same function. Therefore we
can simply always call bwrite().
For our CheriBSD builds we always bootstrap makefs by setting
LOCAL_XTOOL_DIRS='lib/libnetbsd usr.sbin/makefs' and use the makefs binary
from the build tree to create a bootable disk image.

${WORLDTMP}/legacy/usr/libexec will only have libexec/ bits that we've
pushed as bootstrap tools, so this is generally safe to include prior to
PATH. The following are the ramifications of this change:
- BPATH addition gets us at least bootstrap flua in WMAKEENV path for
buildenv, for those earlier systems where it's bootstrapped still
- Reworked the sysent target to just set PATH and let it get worked out in
src.lua.mk or individual sysent makefiles -- this gives us back the
ability to overwrite LUA_CMD and use a different/external lua for these
targets. sysent can also now work cleanly in buildenv.
- tools/build/Makefile will now symlink the host flua into build's host
tools so that the above can work without needing to add the host's
/usr/libexec explicitly into TMPPATH.

flua is bootstrapped as part of the build for those on older
versions/revisions that don't yet have flua installed. Once upgraded past
r354833, "make sysent" will again naturally work as expected.

Inheriting $PATH during the build phase can cause the build to fail when
compiling on a different system due to missing build tools or incompatible
versions somewhere in $PATH. This has cause build failures for us before
due to the jenkins slaves still running FreeBSD 10.
Listing the tools we depend on explicitly instead of just using whatever
happens to be in $PATH allows us to check that we don't accidentally add a
new build dependency.
All tools that do no need to be bootstrapped will now be symlinked to
${WORLDTMP}/legacy/bin and during the build phase $PATH will only contain
${WORLDTMP}. There is also a new variable "BOOTSTRAP_ALL_TOOLS" which can
be set to force compiling almost all bootstrap tools instead of symlinking
them. This will not bootstrap tools such as cp,mv, etc. since they may be
used during the build and for those we should really only be using POSIX
compatible options.
Furthermore, this change is required in order to be able to build on
non-FreeBSD hosts. While the same binaries may exist on Linux/MacOS they
often accept different flags or produce incompatible output.

This has two advantages:
1) We no longer create lots of empty directories that are not needed
2) This is a requirement for building on non-FreeBSD hosts since mtree will
only exist after the bootstrap-tools phase there.

Use tools/build/Makefile to install the headers into ${WORLDTMP}/legacy
instead. Compared to r336026 this has the minor advantage that it avoids
unncessary header installation when building the non-bootstrap libnv.

In order to allow using utimensat() in install(1), add futimens() and
utimensat() to -legacy.
The files futimens.c and utimensat.c are modified copies of the files under
lib/libc/sys/ since the libc versions use symbols that do not exist in the
libc on the build system (sys_futimens and sys_utimensat) . I expect the
next non-sweeping change to both sets of files to be to delete them, anyway.
This will allow reverting r299942 (which is a revert of r299850) enabling
nanosecond timestamps in install(1).

vendors are still using 8.x build platforms, however, so bumping this

or work arounds in one of two places in the tree (src/Makefile.inc1

This removes all the past release compatibilty hacks from various
places in the tree. We still build on tip of stable and current. I

it will just work.
