Because we force enable MK_GCC when building we need to also force
enable it for the cleaning phase. Otherwise the NXB_TARGET files
are found in the next build's kernel-toolchain phase and cause
an error.

Several checks assume .CURDIR is resolved, such as for determining RELDIR from
SRCTOP/.CURDIR. If -C is used then the path is no longer resolved like it was
before which is problematic for symlinked source trees. A similar change was
also made to ports post bmake-20170301.
This fixes 'make -C <symlinked path> buildworld' using the wrong OBJDIR.

This will cause an error if the wanted OBJDIR is not writable. Previously it
would cause the files to generate to the source tree. This was too obscure and
things like buildworld really expect a proper OBJDIR layout.

Using
.symver foo,foo@@VER
causes foo and foo@@VER to be output to the .o file. This requires foo
to be weak since the linker handles foo@@VER as foo.
Using
.symver foo,foo@@@VER
causes just foo@@ver to be output and avoid the need for making foo
weak. It also reduces the constraint on how exactly a linker has to
handle foo and foo@@VER being present.

The OBJS_DEPEND_GUESS mechanism was making vmx_genassym.o depend
on all headers along with vmx_assym.h, though vmx_assym.h depends
on having vmx_genassym.o present to generate. Moving the headers
to DPSRCS is enough to resolve the issue as they will no longer
be implicit dependencies for all objects. Because of this we
need explicit OBJS_DEPEND_GUESS entries to ensure the headers
are generated when needed for the *_support.o files that need
them.

Since Amazon provides NTP servers within their network, this should
be far superior to using the default NTP pools; and since the service
is provided by Amazon there's very little risk in enabling it by
default. (If someone is able to compromise Amazon's NTP servers and
exploit them to attack EC2 instances, they would almost certainly be
able to compromise EC2 instances even without ntpd running...)

Relnotes: EC2 instances now keep their clocks synchronized using
the Amazon Time Sync Service (aka. NTP).
EC2 instances are normally launched with an SSH public key specified,
which is then used for logging in (by default, as 'ec2-user'). Having
ChallengeResponseAuthentication enabled (as FreeBSD's default sshd_config
does) has no functional effect in a new EC2 instance, since you can't log
in using a password until a password has been set -- but having this
enabled results in alerts from automated scanning tools which can detect
that sshd advertises support for keyboard-interactive logins (since they
can't detect that accounts have no password set).
EC2 users who want to use passwords to log in to their instances will need
to set 'ChallengeResponseAuthentication yes' in FreeBSD 12.0 and later.

Inputting fractional non-decimal numbers has never worked correctly in our
OpenBSD-derived dc(1). It truncates the input to a number of decimal places
equal to the number of hexadecimal (or whatever base) places given on the
input. That's unacceptable, because many numbers require more precision to
represent in base 10 than in their original bases.
Fix this bug by using as many decimal places as needed to represent the
input, up to the maximum of the global scale factor.
This has one mildly surprising side effect: the scale of a number entered in
non-decimal mode will no longer necessarily equal the number of hexadecimal
(or whatever base) places given on the input. I think that's an acceptable
behavior change, given that inputting fractional non-decimal numbers never
worked in the first place, and the man page doesn't specify whether trailing
zeros on the input should affect a number's scale.

Previously, lld exited with an error status if the only option given to
the command was -v. GNU linkers gracefully exit in that case. This patch
makes lld behave like GNU.
Note that even with this patch, lld's -v and --version options behave
slightly differently than GNU linkers' counterparts. For example,
if you run ld.bfd -v -v, the version string is printed out twice.
But that is an edge case that I don't think we need to take care of.

Recent DTS (from Linux 4.14) specify a compatible "allwinner,sun50i-h5-ccu"

Add the compatible so later version of u-boot will not fail for us.
This is better than directly changing PCI configuration space of the
device because it makes the PCI bus aware of the configuration.
Also, the change allows to drop a bunch of code that duplicated
pci_enable_msi() functionality.
I wonder if it's possible to further simplify the code by using
pci_alloc_msi().
ivhd should attach after the root PCI bus and, thus, after the ACPI
Host-PCI bridge off which the bus hangs. This is because ivhd changes
PCI configuration of a PCI IOMMU device that is located on the root bus.
If the bus attaches after ivhd it clears the MSI portion of the
configuration. As a result IOMMU event interrupts would never be
delivered.
For regular ACPI devices the order is calculated as
ACPI_DEV_BASE_ORDER + level * 10
where level is a depth of the device in the ACPI namespace.
I expect the depth of the Host-PCI bridge to be two or three,
so ACPI_DEV_BASE_ORDER + 10 * 10 should be a sufficiently safe order
for ivhd.
This should fix the setup of the AMD-Vi event interrupt when vmm is
preloaded (as opposed to kldload-ed).
This ensures that we can receive further event interrupts.
See the description of the bits in the specification for
MMIO Offset 2020h IOMMU Status Register.
The bits are defined as set-by-hardware write-1-to-clear, same as all
the bits in the status register.

In case we are trying to read a catpage, the manpage variable is not defined.
It results in the "cattool" having no arguments.
In case the catpage is compressed, the cattool used is "zcat" which dies if the
standard input is a terminal, meaning the function calling it is exiting as if
there were no ".so"
In case the catpage is uncompressed, the cattool used is "zcat -f" which waits
reading standard input, making the man(1) command hang.

after the kernel and any modules loaded by loader so we can use this to
find the size of the kernel + modules. We can then add on a level 2 page for
the module data and round up the size to be aligned to a level 2 page.
This allows more than 8 MiB of modules to be loaded by loader, e.g. zfs.ko
and opensolaris.ko.
