This commit removes the dependencies on MMU and dynamic libraries.
In order to build v4l2 utilities such as compliancy tools like
v4l2-compliance or cec-compliance, v4-utils can now be built without
dynamic libraries support.
In that case the v4l-utils parts which depends on dynamic library
support are not built:
- libv4l & libv4lconvert libraries
- libv4l plugins
- rds-ctl utility
- contrib test utilities
The rest of the utilities are built.

+Subject: [PATCH] configure.ac: add --disable-libv4l option
+
+Add an option to disable libv4l libraries and plugins compilation.
+If system is not supporting dynamic shared libraries, this option
+is automatically set.
+dlopen() is no more a mandatory dependency (warning is kept).
+lib/ and contrib/ folders are no more built with this option set
+because of libv4l dependency.
+utils/ folder is still built with this options set but without
+rds-ctl because of its libv4l dependency.
+v4l2-compliance and v4l2-ctl are also built but without any links
+on libv4l and libv4lconvert libraries.
