build env you might normally have), stop hacking the bzlib and zlib
sources with sed. There's no longer any need.

Building with the standard system headers isn't a perfect match to the
stand environment. Instead, copy over the files we know are safe to
use and constrain what else is used. We use -nostdinc to achieve this.
This also fixes issues with building 32-bit libraries on amd64
sometimes pulling in the wrong cpufunc.h giving an error now that we
stop on errors. It will also enable an easier transition to lua boot.

latter aren't used. Prefer sys/link_elf.h to link.h so we're only
dependent on the kernel tree. The default installation of link.h just
includes this file, and any benefit from that is outweighed by the
hassle it causes. This reduces the footprint of files needed from the
system includes (or sysroot in buildworld).

Previous to the switch from sys/boot to stand/ zfsboot (used for MBR) did
not support GELI. Now that it is compiled with GELI, it is running out of
space.
zfsldr (which loads zfsboot) was modified to load 256kb in r304321
it's going to be removed soon anyway once the final lingering issues
with kboot are resolved. Go ahead and disconnect it from the build a
little early.

Remove the now-useless dependency on ufsread.c. In some cases, it was
on the wrong file. But in all cases, we now automatically generate

iPXE does insert stub BLOCK IO protocol handle to rework other issues,
this handle is not usable as it does not provide actual implementation.
We can detect this situation by checking and validating the BlockSize
property, so this update does make sure we have BlockSize at least 512B
and its value is power of 2.

The host_open interface was a legitimate mismatch to the userboot
function, while the other pointers didn't need to be non-const.
This makes the powerpc warning free again.

magic number to the kernel in r7 rather than the (currently unused and
irrelevant) width of the metadata pointer, which I believe was intended
for a never-used approach to the 64-bit port. This enables the kernel,
in a future commit, to switch on the cookie to distinguish a real
metadata pointer from loader(8) from garbage left in r6 by some other
boot loader.

greater than 2^31-1, then the result will be huge. This is unlikely,
as we don't support that many sections, but out of an abundace of
caution cast to size_t so the multiplication won't overflow
mysteriously when size_t is larger than 32-bits. The resulting code
may be a smidge larger, but this isn't super-space critical code.

riscv doesn't have -msoft-float. For the moment, just don't add
anything. There's no /boot/loader or other bootstrap contained in the
tree for riscv*. However, with real hardware coming next year, there
are plans for one, so keep building at least a minimal libsa and
ficl to prevent bitrot.

This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2
