pce-fw-builder build fails with "no configuration" error

[srcshelton]

Having followed the instructions at https://github.com/pcengines/pce-fw-builder branch master (and https://github.com/Dasharo/dasharo-pq branch 24.05.00.01), the build-process as documented at https://github.com/pcengines/pce-fw-builder#building-v24050001-or-newer fails with:

Build failed for apu2 with status code 2.

… as a result of build_apus.sh ultimately executing docker run --rm -it -v /usr/src/dasharo/coreboot:/home/coreboot/coreboot -e USER_ID=1000 -e GROUP_ID=100 -v /usr/src/dasharo/pce-fw-builder/ccache:/home/coreboot/.ccache -v /usr/src/dasharo/pce-fw-builder/scripts:/home/coreboot/scripts pcengines/pce-fw-builder:v24.05.00.01 /home/coreboot/scripts/pce-fw-builder.sh 0 true apu2

On the 2.0.1 branch, the result is instead:

+ ./build.sh dev-build /usr/src/dasharo/coreboot apu2 distclean
/usr/src/dasharo/coreboot /usr/src/dasharo/pce-fw-builder
/usr/src/dasharo/pce-fw-builder
 is UNSUPPORTED

… which comes from the line echo "$tag3 is UNSUPPORTED", where tag3 is never defined - although this version doesn't seem to support versions after 4.19 in any case (although this check is broken as there's a trailing . missing, so actually versions matching 4\.{7..19}.* are accepted) 😟

Additionally, the documentation at https://github.com/pcengines/pce-fw-builder/tree/2.0.1#mainline & https://github.com/pcengines/pce-fw-builder/tree/master?tab=readme-ov-file#mainline is out of date, as Dockerfile.ml no longer exists on either branch.

This is because pce-fw-builder's scripts/pce-fw-builder.sh references configs/config.pcengines_$1, but this should be config.pcengines_seabios_$1 for these versions/branches.

Yes, this is a bug. Easy to fix: pcengines/pce-fw-builder@da9951e

I plan to keep this backward compatible only if I get a good reason. Also, pce-fw-builder needs versioning that match releases. I have to introduce that in v24.08.00.01. Since Dasharo (coreboot+UEFI) does not use pce-fw-builder, I may also eliminate it: Dasharo/dasharo-issues#1117.
