These are not used to link the final tool anymore. At some point in the past
the suffix rules changed to not link these in. The original reason for this in
r19176 is unclear but seems to be related to mkdep. The .depend handling is
still broken here as it is for all build tool patterns like this.

- Change the C++ directory entries to honor --sysroot if it is set.
- Don't define CROSS_INCLUDE_DIR for the cross compiler. Instead, set
TARGET_SYSTEM_ROOT to point to WORLDTMP and always define
STANDARD_INCLUDE_DIR.
- Change STANDARD_INCLUDE_DIR and the C++ include directories to just
start with "/usr" always. The compiler will prepend the sysroot when
doing cross-builds. GCC_INCLUDE_DIR (which contains headers that ship
with the compiler such as intrinsincs rather than OS-supplied headers)
remains hardcoded to look in TOOLS_PREFIX.

GCC 4.2 prefixes these directories with --sysroot meaning that during
buildworld they have a double sysroot.

Need to handle LLD_BOOTSTRAP separately (for archs like i386).
This would be much better off with an off-by-default option like
SHARED_TOOLCHAIN that universe force-enabled. Then a normal buildworld
would store the toolchain there if enabled and otherwise in WORLDTMP
with only the 1 arch selected.

This will disable the new LLVM_TARGET_ALL option which will only
enable the required target.
This only impacts the bootstrap compiler in WORLDTMP, not the target compiler
that will be installed.

LLVM_TARGET_* will auto be set based on LLVM_TARGET_ALL and MK_CLANG.
If LLVM_TARGET_ALL is disabled, during a cross-build, then SYSTEM_COMPILER
and SYSTEM_LINKER are auto disabled.
This option should be used by users rather than the per-arch LLVM_TARGET
options as it is simpler to maintain for them should the supported
target list change.

Currently libclang_rt is not provided for cross-building and as such
is not connected to cross-tools. For building clang once in universe
it is likely that libclang_rt won't exist for the universe toolchain
but even if it did it would not support anything but the native arch.
So explicitly check for support before enabling h_raw.

Previously the linuxulator's linux_brk invoked the FreeBSD sys_break
syscall implementation directly. Instead, move the bulk of the existing
implementation to kern_break, and call that from both sys_break and
linux_brk.
This also addresses a minor bug in linux_brk in that we now return the
actual (rounded up) break address, rather than the requested value.

We have a problem with vn_fullpath_global when the file exists. Work
around it by printing the full path if the core file name starts with /,

While useful as an example, veriexecctl, as it is, has very little practical
use, since there is nothing ensuring the integrity of the manifest of hashes.
A more appropriate set of utilities will replace it.
Tested syscalls include rfork(2), chdir(2), fchdir(2), chroot(2),
getresuid(2), getresgid(2), setpriority(2), setgroups(2), setpgrp(2),
setrlimit(2), setlogin(2), mlock(2), munlock(2), minherit(2), rtprio(2),
profil(2), ktrace(2), ptrace(2), fork(2), umask(2), setuid(2), setgid(2),
seteuid(2), and setegid(2). The last six are only tested in the success
case, either because they're infalliable or a failure is difficult to cause
on-demand.

Allow attaching of multiple geli providers at once if they use same
passphrase and keyfiles.
This is helpful when the providers being attached are not used for boot,
and therefore the existing code to first try the cached password when
tasting the providers during boot does not apply.
Multiple providers with the same passphrase and keyfiles can be attached
at the same time during system start-up by adding the following to
rc.conf:
geli_groups="storage backup"
geli_storage_flags="-k /etc/geli/storage.keys"
geli_storage_devices="ada0 ada1"
geli_backup_flags="-j /etc/geli/backup.passfile -k /etc/geli/backup.keys"

2nd 0xffffffff81fdccb0 intrsrc (intrsrc) @ /usr/src/sys/x86/x86/intr_machdep.c:224
There's no need to hold the lock since the cleaning of the interrupt
cannot happen in parallel due to the XNBF_IN_SHUTDOWN flag being set.
Note that the locking in netback needs some improvement or
clarification.
While there also remove a double newline.
