build: make object rule for eolian tests a versioned conditional
automake 1.16 changed the naming of object files: - When subdir-objects is in effect, Automake will now construct shorter object file names when no programs and libraries name clashes are encountered. This should make the discouraged use of 'foo_SHORTNAME' unnecessary in many cases. this requires that object-specific rules must be changed to match the new naming scheme if newer automake is being used. the $am__api_version contains the version string of the automake version used during autoreconf, so this should be checked during configure time in order to generate the correct makefile rule for that automake version other similar rules should be changed in the same way note that this conditional speculates on behavior of automake versions past 1.16, which are not yet released and thus may change, meaning that this issue may reoccur in future automake versions Differential Revision:
