Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

Add support for Exiv2 library and utility to manage image metadata
Exiv2 can be built in GPLv2+ or commercial version. But in commercial
version the Nikon lens name database and the NLS support has to be
disabled for copyright reason.
[Thomas:
- switch to using the CMake build system, which works better than the
clunky autoconf + manual Makefile based build system.
- add missing toolchains dependencies: does not build in static
library configuration, needs C++, etc.]
