Temporarily remove 'make check' from .travis.yml
Temporarily remove 'make check' from .travis.yml

Travis CI failed due to weird reason :

  The log length has exceeded the limit of 4 MB \
  (this usually means that the test suite is raising \
  the same exception over and over).

  The job has been terminated

A temporary solution is removing `make check` and
only perform `make distcheck` to reduce log size.
