FICL definitions not in ficl/ficl32 files broke this generally. This
makes that stuff conditional on BOOT_FORTH. Also, move definitions
related to the architecture (FICL_CPUARCH and friends) into
Makefile.ficl that all parts of the tree that include files with ficl
need to include (but only if MK_FORTH == yes). In addition, had to fix
library ordering issue with LIBSTAND to keep it last. Without boot
forth, there's no references to memset to bring in memset.o from
libstand.a to satisfy libgeliboot.a's use of it. Listing libstand last
solves this issue (and it's the proper place for libstand to boot).

Although this may not be an issue in practice, it would be more correct if the 64-bit version was used. Also, using the 64-bit version would make it easier to add support for 64-bit ubldr on MIPS.

While the later is a better random generator than the former, the main
reason of the change is that random() has a better chance to work with
libstand(3).
At this time we don't include random number generators in bootforth
so this has no effect.

redzone below the stack pointer for scratch space and requires
interrupt and signal frames to avoid overwriting it. However, EFI uses
the Windows ABI which does not support this. As a result, interrupt
handlers in EFI push their interrupt frames directly on top of the
stack pointer. If the compiler used the red zone in a function in the
EFI loader, then a device interrupt that occurred while that function
was running could trash its local variables. In practice this happens
fairly reliable when using gzipfs as an interrupt during decompression
can trash the local variables in the inflate_table() function
resulting in corrupted output or hangs.
Fix this by disabling the redzone for amd64 EFI binaries. This
requires building not only the loader but any libraries used by the
loader without redzone support.
Thanks to Jilles for pointing me at the redzone once I found the stack
corruption.

Export a nunmber of pcibios.X variables into the environment to report

Also implmenet a new command line primitive (pci-device-count), but don't
include it by default just yet, since it depends on the recently added
words and any errors here can render a system unbootable.
This is intended to allow the boot loader to do special things based
on the hardware it finds. This could be have special settings that are
optimized for the specific cards, or even loading special drivers. It
goes without saying that writing to pci config space should not be
done without a just cause and a sound mind.

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.

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.
