"Makefile.in", "*.o", etc. need only be listed in the toplevel .gitignore, the
rules are applied recursively.

Test programs etc. should be listed as "/program" in their directory's
.gitignore, so they are not accidentially ignored in a lower level directory.

If duncontrol detects an installed dune-common module, then it always
assumed that it contains a lib/dunecontrol
subdirectory. Unfortunately, this does not hold for older dune-common
modules and dunecontrol will error out later with a message like

/usr/local/lib/dunecontrol: file not found
Execution of dunecontrol terminated due to errors!

With this commit we fix this by actually checking whether the
lib/dunecontrol subdirectoy exists before adding it to
DUNE_CONTROL_PATH.

Thanks a lot to wuhao sife for reporting this problem.

The variable is was set and used by dunecontrol but not by duneproject.

As we have bumped our compiler requirements to GCC 4.4+, we can now
require the compiler to support C++11.

This patch updates both the autotools and the CMake tests to produce an
error if the compiler doesn't support either -std=c++11 or -std=c++0x.

It also renames the tests from ..0X to ..11 and renames the configure
options from --disable-gxx0xcheck to --disable-cxx11check and removes a
couple of redundant calls to the autotools macro.

clang does not support -print-multiarch. Therefore we try to
extract the "Target:" line from clang -v.

This was lost in the last commit.

duneproject failed miserably when run with only installed modules. With
this patch we correctly setup the pkg-config and dunecontrol path to
handle this situation. In addition we fixed various issues with the newly
created modules and they now build as exspected.

Some ^[$BLANK] or [^[$BLANK]^'], where $BLANK is space followed by tab
did not work as a capturing statement in some cases (e.g. opts files
with CONFIGURE_FLAGS="CXX='bla'"). After this patch we use [$NOBLANK]
with NOBLANK=^$space^$tab which works. In addition the other patches
form feature/posix-sed-dunecontrol have been backported to close flyspray
1401.

With this patch dunecontrol will work even if the path to the module
contains spaces. Unfortunately, the tests for dune modules will still
not work as I could not figure out how to use quoting in the CPP_FLAGS.
