Required to to build dasharo-ec module.

Need to pin SDCC version to 4.2.0 to avoid
Dasharo/dasharo-issues#1785
and be in sync with ec-sdk:
Dasharo/ec-sdk#2

Using 3.8.0 in nix toolchain (as originally used in ec-sdk)
was not feasible:

…mal changes to build Dasharo-EC

Signed-off-by: Thierry Laurion <[email protected]>

- Remove leading tabs from ifeq variable assignments (Make parse error)
- Move post-build steps (cp, dd, touch) out of dasharo-ec_target into
  a proper Make rule; _target is now only make arguments
- Set dasharo-ec_output to ec.rom (the actual artifact, not .built)
- Add -$(BOARD) suffix to dasharo-ec_base_dir and dasharo-ec_dir so
  v540tu and v560tu maintain independent build trees and ec.rom files
- Add explicit rule to copy and zero-pad ec.rom to 128 KB
- Fix coreboot copy rule: use FORCE + cmp so the recipe always runs
  but only updates the destination (and its mtime) when content differs,
  preventing the mtime race between boards sharing coreboot_base_dir

…nges

When the coreboot git commit changes (canary mismatch), remove and recreate
the board-specific build directories to prevent stale artifacts from causing
compilation failures.

This eliminates the need for manual `rm -rf build/x86/BOARD` before rebuilding
after coreboot canary updates in development cycles (when creating patches).

One currently still has to, eg:
echo "bogues repo url + commit hash" | sudo tee /home/user/heads/build/x86/coreboot-25.09/.canary

Current logic then:
1. Detects canary changes and triggers repository cleanup
2. Removes both Heads board directory (build/x86/BOARD) and coreboot board
   directory (build/x86/coreboot-*/BOARD) that contain stale build artifacts
3. Recreates empty board directories for the subsequent build
4. Allows patches to apply cleanly without Ada compilation errors

This ensures Ada builds work correctly after coreboot updates without manual
intervention (resync repo, apply patches, clean artifact dirs and rebuilds only what changed).

…nreleased

The coreboot module for NovaCustom MTL boards was renamed from
'dasharo' to 'dasharo_v56'. The Heads patch system resolves patch
directories as <module_name>[-<patch_version>], so with module
coreboot-dasharo_v56 and patch_version=unreleased the expected path
is patches/coreboot-dasharo_v56-unreleased/.
