Since I don't have guile 2.x installed the problem was immediately
visible.

Here is what I've replied just now in issue #5830:

  If you want to override `pkg-config`, use either the environment
  variables `GUILE_CFLAGS` and `GUILE_LIBS` or create a new directory
  for `.pc` files that gets prepended to the standard directory list
  with the `PKG_CONFIG_PATH` environment variable.  If the standard
  directory list still makes problems you can use the
  `PKG_CONFIG_LIBDIR` environment variable to override that, too.

In other words, create two directories for the guile-2.2 and guile-3.0
`.pc` files and use PKG_CONFIG_PATH to prepend the needed one to the
directory search list.
