package/libv4l: allow build of v4l2 utilities on noMMU platforms

Browse source 
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: revisit v4l2-ctl/compliance using libv4l
variable naming
USE_V4L2_CTL and USE_V4L2_COMPLIANCE are used to trig the fact that
v4l2-ctl and v4l2-compliance are using libv4l2, change namings to not
confuse with overall v4l2-ctl/compliance utilities building.

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.
