d927d443e1 Mark the func pointer as __dead2. It looks up loader_main, which
either aborts or exits, but never returns. Tag it as a non-returning
function rather than supply a bogus return(0) at the end of main.

db71174436 Fix theoretical integer overflow issues. If the product here is
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.

cdadbf0971 loader.efi: efipart does not recognize partitionless disks
Rework the block device handle check to allow more robust device
classification. This is mostly usability issue - it can be quite confusing
for user when no disks are listed with lsdev.

Add more comments about what and why is done.

063e16324b Unbreak riscv build in universe.
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.

01dd1497ec Fix gptzfsboot for cases with GELI.
HAVE_GPT isn't currently a thing, but HAVE_GELI is. Replace the former
with the latter and remove util.o from the build list (it's picked up
from libsa/libsa32, and that's OK).

8a4217aacf Move some more common stuff up to Makefile.inc. In particular, the no
simd / no float stuff is centeralized here. Also centralise
-ffreestanding since it is specified everywhere.

This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2
in CFLAGS_NO_SIMD should fix building for newer machines (eg with
CPUTYPE=haswell) where clang was generating avx2 instructions.
