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.
In the freestanding boot compile environment, standard headers are not
available. Curiously, only building with clang exposed this as compiles
with external GCC still succeeded.

The __dmadat variable is a statically allocated I/O buffer. The type is
declared in the ufsread.c source file and clang warns if a variable is
defined before it's type is declared.

The beri boot loaders depend on symbols defined in linker scripts or
assembly files. The boot loaders do not care about the type of these
symbols but just want to extract a pointer to them. Older versions of
GCC permitted external symbols to be declared of type 'void' and then
'&foo' generated a void pointer to the memory at the symbol's address.
However, void objects are not valid C and newer versions of GCC error if
these are used. Instead, declare these symbols as being bytes (or
an array of bytes in the cheri_sdcard_vaddr case).

Prior to r325114, bsd.init.mk was included after assignments to CFLAGS and
LDFLAGS in these Makefiles. After r325114, bare assignments (= rather than
+=) lost system-assigned default values that are needed when compiling with
an external toolchain. CFLAGS in both Makefiles already uses +=. This
commit changes LDFLAGS to use +=. While here, depend on the LDFLAGS update
in the parent Makefile.inc to set -nostdlib.

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.

weren't needed, and their existance interfered with things in subtle
ways. One of these subtle ways was that malloc could be different
based on what files were included when (even within the same .c file,
it turns out). Move to a single malloc implementation as well by
adding the calls to setheap() to gptboot.c and zfsboot.c. Once upon a
time, these boot loaders strove to not use libstand. However, with the
proliferation of features, that striving is too hard for too little
gain and lead to stupid mistakes.
This fixes the GELI-enabled (but not even using) boot environment. The
geli routines were calling libstand malloc but zfsboot.c and gptboot.c
were using the mini libstand malloc, so this failed when we tried to
probe for GELI partitions. Subtle changes in build order when moving
to self-contained stand build in r326593 toggled what it used from one
type to another due to odd nesting of the zfs implementation code that
differed subtly between zfsloader and zfsboot.

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.

Move kernel includes and libsa includes together at the top of defs.mk
Move all machine specific defines from Makefile.inc to their friends
in defs.mk.
Add comments and remove now useless junk after the move.

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.
