upgrade to automake 1.11

[Peter]

At time of writing automake 1.11 has not been released, so there is no plan to upgrade version requirement. The primary reason for the ticket is to list new useful features in v1.11 that we can start to use when developers have agreed v1.11 is available on their various systems.

• The default source file extension (.c) can be overridden with AM_DEFAULT_SOURCE_EXT now. This implies that test/Makefile.am​ can be significantly reduced since all SOURCE have extension (.cc).

• The "deleted header file problem" for *.m4 files is avoided by stub rules. This allows 'make' to trigger a rerun of 'aclocal' also if some previously needed macro file has been removed. This implies workaround in Makefile.am​ could be removed.

[Peter]

The test suite is extensively expanded in automake 1.11. See link below for a short tour ​http://lists.gnu.org/archive/html/automake/2009-05/msg00124.html

[Peter]

I noticed that automake 1.11 is now available at thep, so I see no reason to wait with this upgrade.

Besides the points mentioned above I'd like to use the new test-suite and the color-tests is also a nice feature.

Any opposition?
