bootstrap: fix to work with latest autotools

Patch from Stefano Lattarini <stefano.lattarini@gmail.com>
Use parallel tests harness, to fix make check with newer automake.

* configure.ac (AM_INIT_AUTOMAKE): Add the 'parallel-tests' option.
Also, require Automake >= 1.11.1, since that option was only introduced
in the 1.11.x, and Automake 1.11 should not be used because it suffered
from few serious bugs.
(AC_PREREQ): Require Autoconf 2.62, since that is the minimal version
required by Automake 1.11 anyway.
* tests/Makefile.am (TESTS_ENVIRONMENT): Split into ...
(AM_TESTS_ENVIRONMENT, LOG_COMPILER): ... these two, and adjust to the
slightly different APIs.
tests/Makefile.am: add a missing backslash
