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.
This is the final step required allowing to compile and to run RISC-V
kernel and userland from HEAD.
RISC-V is a completely open ISA that is freely available to academia
and industry.

Go ahead and defined -D_STANDALONE for all targets (only strictly
needed for some architecture, but harmless on those it isn't required
for). Also add -msoft-float to all architectures uniformly rather

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

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.

bootloader. Implement the following routines:
pcibios-device-count count the number of instances of a devid
pcibios-read-config read pci config space
pcibios-write-config write pci config space
pcibios-find-devclass find the nth device with a given devclass
pcibios-find-device find the nth device with a given devid
pcibios-locator convert bus device function ti pcibios locator
These commands are thin wrappers over their PCI BIOS 2.1 counterparts. More
informaiton, such as it is, can be found in the standard.
Export a nunmber of pcibios.X variables into the environment to report
what the PCI IDENTIFY command returned.
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.

as is done with libstand32. The native 64-bit ficl will be used by the

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.

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.
