[flashrom] Makefile removal is imminent

[Peter Marheine]

Hi everyone,

As was described in the release notes for version 1.4, I plan to remove the
Makefile soon and make Meson the only supported buildsystem for flashrom:
the proposed change is https://review.coreboot.org/c/flashrom/+/83673

If you haven't tried using meson before, now would be a good time to try
and ensure your preferred workflow is still supported. If something you
depend on doesn't work with meson, I'd love to hear about it so we can try
to continue supporting it. Otherwise, I expect we'll be merging the above
change within a few weeks to make good on our promise of removing support
for building with make.
