Add kconfig to use blobs on 24.12 boards coreboot configs and proper build output to console

[tlaurion]

• Fixes Build fails for t420-maximized/t430-maximized : microcode update file creation race condition (empty when trying to inject in CBFS in final rom stitching step) #1940 by adding CONFIG_USE_BLOBS=y in all boards that switched from coreboot 24.02.01 tarball release to coreboot fit repo with 24.12 (race condition introduced under Coreboot version bump 24.02.01 -> 24.12 for most board + Thinkpad T480 addition (coreboot upstream in WiP state) #1908)
• Makefile: have coreboot git repo actions be more verbose on console output
• Other coreboot configs: saved in oldconfig format so that config is as used by coreboot (see fe4b5e6 commit log for repro)

@JonathonHall-Purism @miczyg1 please review!

When rebuilding a target after cleaning up the coreboot repo under build/x86/coreboot-24.12 I also get:

mkdir -p "/home/miczyg/heads/build/x86/libgpg-error-1.46/"
tar -xf "/home/miczyg/heads/packages/x86/libgpg-error-1.46.tar.bz2" --strip 1 -C "/home/miczyg/heads/build/x86/libgpg-error-1.46/"
if [ -r patches/libgpg-error-1.46.patch ]; then ( git apply --verbose --reject --binary --directory build/x86/libgpg-error-1.46 ) < patches/libgpg-error-1.46.patch || exit 1 ; fi

Another module not cleaned properly?

Yes: same issue for files created by patches as for your other comment #1943 (comment)

Heads creates some files through patches/* files and therefore why the dev cycles helpers in global Makefile :/

heads/Makefile

• rm build/x86/libgpg-error-1.46/src/syscfg/lock-obj-pub.powerpc64le-unknown-linux-musl.h needs to be removed manually (not git repo here: tarball+ patch applied for muslc ppc64)
• rm -rf build/x86/coreboot-24.12/src/mainboard/lenovo/sklkbl_thinkpad/variants/t480s since the bin files created for t480s by unmerged t480 patchset are bin files created.

The ther Makefile global dev cycles helpers will radically remove more artifacts, and consequently take more time to rebuild rom to be tested :/

The alternative of using helpers is to nuke the heads dir and start fresh from git clone. I have not found better alternatives if patches are not upstreamed, which is one of the many reasons I push so much for patches to be upstreamed.

[tlaurion]

Still working on the helper to have patches reversal working properly.

[tlaurion]

ready

Will be fixed by #1952 separate issue

[tlaurion]

Waiting for build to succeed to merge.
