Not if we use your suggested snapshot tarball, which rightly lack a .git
directory. There is no way for the build system to divine the version
number at build time with ‘git describe’.

Unpatched mcelog, manually built from ‘guix download’ed sources, would
report its version as ‘unknown’. With this snippet, it just works.

Kind regards,
