The release notes for Automake 1.11 say:

  "subdir-object mode works now with Fortran ..."

Your Makefile is clearly depends on the subdir-object feature (typical
for non-recursive setups), so it appears that you must require Automake
1.11 at minimum.  Your SUSE install only has Automake 1.10.1.

This is normally not a huge problem as it is normally only necessary to
run automake when (re)generating the build system; this is not something
users building from a release tarball will ordinarily need to do.

Hope that helps,
