SeaBIOS is known to hang on this board. It is being investigated.

Add two variable options for target.cfg files:

* seabiosname
* grubname

This string defines where it would be located in CBFS.

I also added a "cleanargs" argument, similar to the makeargs
argument, to work around a build error.

This builds the PCSX-Redux PS1 BIOS. They reverse engineered
the Sony PS1 BIOS and wrote a free one under MIT license.

Run this:

./mk -b pcsx-redux

The file will appear: bin/playstation/openbios.bin

single-tree projects cannot be handled in bulk, e.g.
./mk -f project1 project2 project3

that is still the case, from the shell, but internally
it is now possible:
mk -f project1 project2 project3

mk() is a function that simply handles the given flag,
and all projects specified.

it does not handle cases without argument, for example
you cannot do:
mk -f

arguments must be provided. it can be used internally,
to simplify cases where multiple single-tree projects
must be handled, but *also* allows multi-tree projects
to be specified, without being able to actually handle
trees within that multi-tree project; so for example,
you can only specify coreboot, and then it would run
on every coreboot tree.

this is another alternative to the previous fix. this one
is therefore now a pre-emptive fix, in case other code is
written in the future that makes use of badhash.

the badhash variable in a y/n variable, so initialise to n.

XBMK_CACHE is now used, instead of hardcoding cache/

this is exported initialised to cache/, if unset.
this means you can set your own directory, and it means
./update release will use the same directory.

this means bandwidth wastage is further avoided.

if coreboot itself is being handled, crossgcc has the
correct makeargs, setting the number of build threads.

however, other projects can specify "xtree" pointing to
a given coreboot tree, and build crossgcc for it.

one workaround may be to use trees -d coreboot TREE,
but then extra code would have to be written to make
it avoid other things like building cbfstool, which is
not required for just building crossgcc.

the cleanest way to do it is to simply hardcode it. the
value is set exactly the same as regular coreboot makeargs.

this fixes a bug, where some builds of crossgcc are made
on a single thread, rather than using XBMK_THREADS. this
patch forces it to always use CPUS=$XBMK_THREADS

we no longer need to remove cache/ per project, because
it's removed in bulk at the end, in the main build script,
when generating release archives.

hash/ becomes cache/hash/

repo/ becomes cache/repo/

actual source code is not scanned, but config directories are
scanned. simply get the checksum of each file under config/
pertaining to a given project/tree, and also for the given
target. coreboot utilities are also handled.

if it changes, in any way, delete and re-build automatically.

such deletions should probably still be done manually, as part
of understanding the build system, but this change should make
the build system much easier to use during development.
