Description: modernise automake
 Recent automake defaults to running tests in parallel which redirects
 `make check` output to log. Setting "serial-tests" restores old behaviour.

 automake: warning: possible forward-incompatibility.
 automake: At least a source file is in a subdirectory, but the 'subdir-objects'
 automake: automake option hasn't been enabled.  For now, the corresponding output
 automake: object file(s) will be placed in the top-level directory.  However,
 automake: this behaviour will change in future Automake versions: they will
 automake: unconditionally cause object files to be placed in the same subdirectory
 automake: of the corresponding sources.
 automake: You are advised to start using 'subdir-objects' option throughout your
 automake: project, to avoid future incompatibilities.
