The benefit now is that it can be cleaned. E.g.

./update project build -b coreboot utils
./update project build -b coreboot utils default
./update project build -c coreboot utils
./update project build -c coreboot utils default

the update/project/build script checks when arguments
are provided after the project name. if the first one
is "utils", then it acts in the same way as the old
build/coreboot/util script

build/release/src was partly re-written to accomodate this

memtest86plus was patched to have a central Makefile, and
lbmk modified to use that, rather than mess with build32
and build64. the central Makefile just builds both targets
or cleans both targets

Instead of having detailed error messages, run most
commands through a function that calls err() under
fault conditions.

Where detail is still required, err() is still called
manually. Where it isn't, the error message is simply
whatever command was executed to cause the error.

This results in a massive sloccount reduction for lbmk;
specifically, 178 sloc reduction, or a 8.1% reduction.
The total sloccount is now 2022, for shell scripts.

also, some of them were out of date; years now updated.

This results in much cleaner copyright and license declarations.
SPDX headers are legally recognised and make auditing easier.

Also, remove descriptions of each script, from each script.
Libreboot documentation at docs/maintain/ describes them.
