Only for software using Libtool.  For example, this works:

  guix build intel-mpi-benchmarks --with-input=openmpi@4=openmpi@5

This particular package uses CMake, which is more common than Autotools
in this domain.

Maybe someday we’ll just remove .la files wholesale, as Debian and
others have been doing for a while.
