d1be0bf24e Use CFLAGS_NO_SIMD in preference to varying lists of -mno-xxxx flags.
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
that higgley piggley like it is today.

008d7c831f Add META_MODE support.
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.

463cde4030 The System V ABI for amd64 allows functions to use space in a 128 byte
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.

ea3c3dd245 Add support for calling pcibios routines from the
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.

fcb180b479 Give mips64 its own ficl configuration that sizes pointers/etc suitably for
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.

ed44436fe1 Fix the build of the testmain target. This target compiles a Forth
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.

fcb95347ba Add 2 builtin words for working with directories:
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.

8131f8e4f6 boot: use -march=i386 for both i386 and amd64 builds
.. 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.

f656f9bc4c Try to avoid all files dependence on the modification time of the large and
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.

ade9ba91cb Update to FICL 3.03 (the last release before FICL4 rewrite).
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.
