this avoids writing the version/versiondate files as root.
this complements the previous fix, that avoided writing those
same files when running the dependencies command.
initial setup of the build system requires root, to run the
dependencies script, but otherwise the build system prevents
running as root for everything else, so we must avoid writing
the version/versiondate files as root.
that same avoidance is necessary when checking whether running
other commands as root; ironically, this check then prevented
running the build system at all!
the bug should be fully fixed now. i found this quite by accident
the other day, when testing something else.
good thing this got fixed because the release!

do it strategically, in just the right place so that the
version and versiondate files aren't written.
otherwise, version/versiondate are written as root and
the build system becomes unusable after that, unless you
reset the file ownerships from root. hardly user-friendly.
mitigate this bug.

already of saying "found", say "already exists"
this means the output of these commands more user
friendly and intuitive:
./update trees -b grub default
./update trees -b coreboot i945
this is just an example. when an ELF file already
exists, the build is skipped even if src isn't downloaded.
this design is intentional, because it means that you can
use previous builds if you want to save time on another.

adding help again is a bad idea. code should never
document itself; that's what documentation is for.
so, make the code do a better job telling the user
where to find documentation.

The xHCI patches were removed because they caused issues
on Sandybridge-based Dell Latitude laptops. See:
https://codeberg.org/libreboot/lbmk/issues/216
The issue was not reported elsewhere, but we still don't
need xHCI support in Canoeboot's GRUB because none of the
available coreboot targets have xHCI support. However, we
may want it in the future and it helps to keep Canoeboot
in sync with Libreboot (this patch is adapted from lbmk).
Each given coreboot target can say which GRUB tree to use
by setting this in target.cfg:
grubtree="xhci"
In the above example, the "xhci" tree would be used. Some
generic GRUB config has been moved to config/data/grub/
and config/grub/ now looks like config/coreboot/ - also,
the grub.cfg file (named "payload" in each tree) is copied
to the GRUB source tree as ".config", then added to GRUB's
memdisk in the same way, as grub.cfg.
Several other design changes had to be made because of this:
* grub.cfg in memdisk no longer automatically jumps to one
in CBFS, but now shows a menuentry for it if available
* Certain commands in script/trees are disabled for GRUB,
such as *config make commands.
* gnulib is now defined in config/submodule/grub/, instead
of config/git/grub - and this mitigates an existing bug
where downloading gnulib first would make grub no longer
possible to download in lbmk.
There is another reason for merging this design change from
lbmk, and that reasoning also applies to lbmk. Specifically:
This change will enable per-board GRUB optimisation in the
future. For example, we hardcode what partitions and LVMs
GRUB scans because * is slow on ICH7-based machines, due
to GRUB's design. On other machines, * is reasonably fast,
for automatically enumerating the list of devices for boot.
Use of * (and other wildcards) could enable our GRUB payload
to automatically boot more distros, with minimal fuss. This
can be done at a later date, in subsequent revisions.
