Alter bsd.compat.mk to set MACHINE and MACHINE_ARCH when included
directly so MD paths in Makefiles work. In the process centralize
setting them in LIBCOMPATWMAKEENV.
Alter .PATH and CFLAGS settings in work when the Makefile is included.
While here only support LIB32 on supported platforms rather than always
enabling it and requiring users of MK_LIB32 to filter based
TARGET/MACHINE_ARCH.
The net effect of this change is to make Makefile.libcompat only build
compatability libraries.

interface has changed.
During vlan reconfiguration without destroying interface, it is possible,
that parent interface will be changed. This usually means, that link
layer address of vlan will be different. Therefore we need to update all
associated with vlan's addresses permanent llentries - NDP for IPv6
addresses, and ARP for IPv4 addresses. This is done via lladdr_task
execution. To avoid extra work, before execution do the check, that L2
address is different.

During the port of MMP (illumos bug 10499) from ZoL, I found this
earlier ZoL project is a prerequisite. Here is the original
description. This addition will enable us to sync an open TXG to the
main pool on demand. The functionality is similar to 'sync(2)' but
'zpool sync' will return when data has hit the main storage instead of
potentially just the ZIL as is the case with the 'sync(2)' cmd.

[x86] avoid crashing when splitting AVX stores with non-simple type
(PR43916)
The store splitting transform was assuming a simple type (MVT), but
that's not necessarily the case as shown in the test.
This should fix 'Assertion failed: (isSimple() && "Expected a
SimpleValueType!")' when building the security/openssl111 port targeting
a CPU that supports AVX, but not AVX2, such as sandybridge.

There doesn't seem to be much sense in defaulting "on" unwind tables on
amd64 and not on other arches. It causes surprising differences between
platforms, such as the PR below.
Prior to this change, FreeBSD inherited the default implementation of the
method from the Gnu.h Generic_Elf => Generic_GCC parent class, which
returned true only for amd64 targets. Override that and opt on always,
similar to, e.g., NetBSD.

In the past, we would add symbolic links for MACHINE_CPUARCH when it differed
from MACHINE. This was for pc98 only, however. All other architectures didn't
need this and it was really due to pc98 pulling from i386 rather than something
more intrinsic. At the time, we had the split we did to mimic what NetBSD did
for its 68k ports where many different kernels were possible for the same
architecture. Since then, both projects have moved away from this convention to
having a more generic MACHINE for each architecture. FreeBSD's new arm64/aarch64
breaks this old notion and so was an exception to the rule. So, we no longer
need to create this link for any old machine or any new machine, delete it
entirely.

Also, fix pmap_change_attr() to ignore non-kernel mappings.
* Fix a masking bug in mmu_booke_mapdev_attr() which caused it to align
mappings to the smallest mapping alignment, instead of the largest. This
caused mappings to be potentially pessimally aligned, using more TLB
entries than necessary.
* Return existing mappings from mmu_booke_mapdev_attr() that span more than
one TLB1 entry. The drm-current-kmod drivers map discontiguous segments
of the GPU, resulting in more than one TLB entry being used to satisfy the
mapping.
* Ignore non-kernel mappings in mmu_booke_change_attr(). There's a bug in
the linuxkpi layer that causes it to actually try to change physical
address mappings, instead of virtual addresses. amd64 doesn't encounter
this because it ignores non-kernel mappings.
With this it's possible to use drm-current-kmod on Book-E.
