The 32-bit bootloaders on amd64 now use the 32-bit version in ficl32,
as is done with libstand32. The native 64-bit ficl will be used by the
upcoming UEFI loader.

while this won't actually be used for anything (yet), it doesn't hurt to
ensure it is exposed to the tinderbox.

a 64-bit architecture, rather than trying to share the 32-bit MIPS ficl
configuration.
When building ficl on MIPS, don't conflate 32-bit and 64-bit ISAs -- unlike
x86, we don't want a 32-bit loader on a 64-bit CPU. Use quite conservative
code generation -- e.g., softfloat, no GOT, etc -- suitable for early boot.

interpreter that can be run on the system and as such cannot be
compiled against libbstand. On the one hand this means we need to
include the usual headers for system interfaces that we use and
on the the other hand we can only use standard system interfaces.
While here, define local variables only when needed to make this
WARNS=2 clean on amd64.

isdir? ( fd -- bool )
freaddir ( fd -- ptr len TRUE | FALSE )
The 'isdir?' word returns `true' if the file descriptor is for a
directory and `false' otherwise.
The 'freaddir' word reads the next directory entry and if successful,
returns its name and 'true'. Otherwise 'false' is returned.
These words give the loader the ability to scan directories and read
files contained in them for 'rc.d'-like flexibility in handling which
modules to load and/or which tunables to set.

(ARM uses 'int' and 'unsigned'; i386 uses 'long' and 'unsigned long'),
so we need explicit casts to long and unsigned long here to ensure
that the result matches the printf %ld and %lx specifiers.
.. so that consistent compilation algorithms are used for both
architectures as in practice the binaries are expected to be
interchangeable (for time being).
Previously i386 used default setting which were equivalent to
-march=i486 -mtune=generic.
The only difference is using smaller but slower "leave" instructions.

often modified directory created symbolic links points to - it cause
unnecessary full rebuilds each time make runs when directory is changed.
So do it only if symbolic link does not exists, which usually means that
objdir is clean anyway.

This uses the common U-Boot support lib (sys/boot/uboot, already used on
FreeBSD/powerpc), and assumes the underlying firmware has the modern API for
stand-alone apps enabled in the config (CONFIG_API).
Only netbooting is supported at the moment.

The relevant changes for FreeBSD (excerpt from the release note):
* Newly implemented CORE EXT words: CASE, OF, ENDOF, and ENDCASE. Also
added FALLTHROUGH, which works like ENDOF but jumps to the instruction
just after the next OF.
* Bugfix: John-Hopkins locals syntax now accepts | and -- in the comment
(between the first -- and the }.)
* Bugfix: Changed vmGetWord0() to make Purify happier. The resulting
code is no slower, no larger, and slightly more robust.
The whole problem seems to be size. Which is odd, because it is said
that size doesn't matter. Anyway... Add -Os to strategic places in the
makefile to have the final loader be as mall as possible. This seems
to be enough to make it work. For now... I think something is more
fundamentally wrong; or something more fundamental is wrong. Potato,
potaato.
very pervasive in this code. This fixes a few of those assumptions and
band-aids over some others.
