A foolish consistency is the hobgoblin of little minds, adored by
little statesmen and philosophers and divines. With consistency a
great soul has simply nothing to do. -- Ralph Waldo Emerson
Summary:
All metadata.c files are very similar, with only trivial changes. Unify them
into a single common file, with minor special-casing where needed.

preference to LIBFICL{,32}. LIBFICL{,32} are now always defined, but
LDR_INTERP{,32} is defined empty when building w/o forth (aka the
simple interpreter) and defined to LIBFICL{,32} when we are building
forth.
MK_CTF, MK_SSP, MK_PROFILE, NO_PIC, and INTERNALLIB are always the
same, so set them in defs.mk. MAN= is common, so set it here too.
This removes a lot of boring repetition from the Makefiles that added
almost no value.
On POWER8 with current petitpoot, the loader.kboot might be
run as little-endian application. The FreeBSD kernel is
always big-endian, so the load_elf_* routines must be aware
of proper endianness of all fields.

removing this argument, and expanding when rc is NULL. This
effectively completes the back out of custom scripts for tftp booted
loaders from r269153 that was started in r292344 with the new path
tricks that obsoleted it.

HELP_FILES is a loader only thing, so move it to loader.mk. Only
generate the help file if HELP_FILES is defined. Adjust Makefiles to
new convention. Fix a few cases where ${.CURDIR}/ was missing
resulting in missing bits from the help files.

Don't print when we can't find a file. Copy it instead to the error
buffer. Higher level routines determine if it's appropriate to print
the error message.
Also, remove dead code (labeled bogusly lost functionality) since we
never used that functionality. Remove unused arg from interact() too.

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.

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.
