only adds support for kernel-toolchain, however it is expected further
changes to add kernel and userland support will be committed as they are
reviewed.
As our copy of binutils is too old the devel/aarch64-binutils port needs
to be installed to pull in a linker.
To build either TARGET needs to be set to arm64, or TARGET_ARCH set to
aarch64. The latter is set so uname -p will return aarch64 as existing
third party software expects this.

This fixes C++ libraries not implicitly linking in libc++. This is
generally not an issue because the final linking with the compiled binary
will involve CXX via PROG_CXX or other means. It is however
inconsistent with libraries implicitly linking in libc and problematic
for trying to build libraries with '-z defs' to ensure all direct
dependencies are linked in.
libatf-c++ is currently the only consumer of this new feature.

The compilation lines are not hidden and there is not much reason to
hide the linker line. It is useful to see.

which includes more than one file with the same name, in different
directories.
For example, setting:
SRCS+= foo/foo.c bar/foo.c baz/foo.c
will now create separate objdirs 'foo', 'bar' and 'baz' for each of the
sources in the list, and use those objdirs for the corresponding object
files.

any defaults or user specified actions on the command line. This would
be useful for specifying features that are always broken or that
cannot make sense on a specific architecture, like ACPI on pc98 or
EISA on !i386 (!x86 usage of EISA is broken and there's no supported
hardware that could have it in any event). Any items in
BROKEN_OPTIONS are forced to "no" regardless of other settings.
Clients are expected change BROKEN_OPTIONS with +=. It will not
be unset, so other parts of the build system can have visibility
into the options that are broken on this platform, though this
should be very rare.

function component of an SDT probe. Currently, the module component is
filled in automatically if left unset; this is not yet true for the function
component, but will be addressed by some ongoing work.

in kern_gzio.c. The old gzio interface was somewhat inflexible and has not
worked properly since r272535: currently, the gzio functions are called with
a range lock held on the output vnode, but kern_gzio.c does not pass the
IO_RANGELOCKED flag to vn_rdwr() calls, resulting in deadlock when vn_rdwr()
attempts to reacquire the range lock. Moreover, the new gzio interface can
be used to implement kernel core compression.
This change also modifies the kernel configuration options needed to enable
userland core dump compression support: gzio is now an option rather than a
device, and the COMPRESS_USER_CORES option is removed. Core dump compression
is enabled using the kern.compress_user_cores sysctl/tunable.

DS3231 has a temperature sensor, an independent 32kHz output (which can be
turned on and off by the driver) and another output that can be used as
interrupt for alarms or as a second square-wave output, which frequency and
operation mode can be set by driver sysctl(8) knobs.
