It is always a good idea. In one case, attempting to allocate N+1 PMCs
from a class with N hardware counters would incorrectly attempt to
allocate from the next class in the list. Without this validation, this
can lead to all kinds of strange behaviour.
Since powerpc_allocate_pmc() is used by both the mpc7xxx and ppc970
classes, add a new global to track which is active (it will never be
both).

When executing strip(1), '--' is passed as an argument to explicitly
terminate the getopt(3) loop. The option parsing in llvm-strip doesn't
support this however, so setting XSTRIPBIN=llvm-strip results in an
unsupported argument error. llvm-strip(1) is otherwise
commandline-compatible with FreeBSD's strip(1), so just use the
documented argument format that is common to both.
Special care needs to be taken for filenames beginning with a '-'.

Clang 13 produces the following warning for hammer_time_xen():
sys/x86/xen/pv.c:183:19: error: the pointer incremented by -2147483648 refers past the last possible element for an array in 64-bit address space containing 256-bit (32-byte) elements (max possible 576460752303423488 elements) [-Werror,-Warray-bounds]

^
This is because the expression first casts start_info->modlist_paddr to
struct hvm_modlist_entry * (via vmpaddr_t), and *then* adds KERNBASE,
which is then interpreted as KERNBASE * sizeof(struct
hvm_modlist_entry).
Instead, parenthesize the addition to get the intended result, and cast
it to struct hvm_modlist_entry * afterwards. Also remove the cast to
vmpaddr_t since it is not necessary.

The ZTS block_device_wait helper function should use -e when waiting
for a file to appear since it will be either a block special device
or a symlink. This didn't cause any failures but when a device path
was specified the function would wait longer than needed.
Additionally update the most flakey test cases to pass the file path
to block_device_wait to try and improve the test reliability. The
udev behavior on Fedora in particular can result in frequent false
positives.

Clang 13.0.0 now has a -Wunused-but-set-variable warning similar to the

small binary size required. Luckily clang 13.0.0 does not need any
