function they occured in, allowing for easier debugging.

sloccount 2303 in lbmk. that's still only slightly bigger
than libreboot 20260907 which was 2180, and still much
smaller than libreboot 20230625 which was 3322.
this is *without* the condensed codelines, so now the only
thing that's reduced is the overall amount of logic present
in the build system.
and i should clarify that lbmk is presently much more powerful
than both of those two versions (20160907/20230625).
the 2016 one is useful for comparison historically, since that
was the last major version of libreboot prior to the great
second coming of leah in 2021; and the 2023 june release was
basically the last one before the great audits of 2023 to
2025 began.
not to brag (not much anyway), but all of this means that lbmk
is an insanely efficient build system, considering all the
features it has and what it does.
i unrolled the condensed code style in lbmk, making the scripts
a lot easier to read, because i received complainst about the
condensed style previously used; nicholas chin and alper nebi
yasak both told me that it sucked, and riku viitanen had hinted
at that same fact several months prior.
so hopefully now, lbmk is a bit nicer. those and other people
often find it challenging to challenge me because for reason
they assume i'll get upset and fly off the handle, but it's the
opposite. i want constant criticism, so that i know to improve!

the newer way handles escaped characters better, and it
can be nested more easily. it's also more readable.
personally, i prefer the old way, because it's more
minimalist, but it occurs to me that a lot of people
nowadays don't know about backticks, but they do know
of the modern way.
to make the code more readable, i have modernised it.

instead, create a file indicating that a given xgcc

if e.g. elf/coreboot/default/w500_16mb contains readied
images from before, crossgcc is still being checked.
if you already built all the coreboot images, and wanted
to just modify all the payloads for example, this would
result in a much slower re-build process, because it is
needlessly re-checking crossgcc every time.
by doing it this way, we need up the testing of payloads
quite considerably, during xbmk development.

The current logic deletes old project files e.g. sources,
but *after* updating the project hash.
This means that if a deletion fails, and the directory
is still there (e.g. src/coreboot/default/) afterward, it's
now a tainted archive, yet the hash has been updated, so
subsequent runs of the build system will cause unknown
errors.
This patch fixes that, by first copying the new hash to
a temporary file. *Then*, deletions are handled, and the
final hash file is updated afterward.
The code is now a bit more bloated as a result, but this will
reduce the risk of tainted sources being handled under fault
conditions.

in that case, the previous tree-wide check will cover
it, so the current logic wastes computational time.

Detect when a config changes. This is done even if the
entire tree doesn't change.
This is already done per-tree if files change, but
individual project files don't change.
For example, if a grub.cfg changes, the given cached
build for that GRUB tree isn't deleted. Same thing if
a given U-Boot config doesn't change.
This patch fixes a longstanding design flaw of lbmk,
making auto-re-builds more reliable. This complements
another recent change, that deletes all target builds
of a given tree when the tree changes.

Target builds go inside a common directory for
the given tree now, which gets deleted, thus
deleting all target builds of that given tree.
Therefore, the deletion being removed is redundant.

as opposed to target/
for example:
image the command:
./mk -b u-boot amd64coreboot
This would put the U-Boot binaries here:
elf/u-boot/amd64coreboot/default/
With this change, they now go here:
elf/u-boot/x86_64/amd64coreboot/default/
This solves a problem that existed previously, where
you could modify a given tree in a multi-tree project,
but cached builds for targets branching separately off
of each tree would not be deleted, and thus not re-built.
This accomplishes such a result, without needing to
further check hashes of individual targets.
The latter will still be done, in a future change, because
this change doesn't fix another problem:
If you change a given config, e.g. targetname "foo" which
uses tree "bar", elf/foo/ would not be removed automatically
for re-build.
So this change only deletes individual target builds when
their master tree changes.
Where the target and tree are the same, this also means
elf/tree/target/
for example: seabios/default would create binaries in:
elf/seabios/default/default/
not:
elf/seabios/default/
