When cross-compiling c4group should be build for the host
machine before building OpenClonk for the target.
Without C4GROUP_TOOL_ONLY option, we have to build OpenClonk
for the host.
C4GROUP_TOOL_ONLY allow to build only c4group tool for the
host.

With this patch I can build OpenClonk with Buildroot.
While cross-compiling, it is easier to find a binary
from the patch using FIND_PROGRAM instead of using
a cmake file.
Try to find c4group native tool with FIND_PROGRAM and
fallback to the cmake file if c4group is not found.

As reported by [1], some distributions use shared libraries as
default preset in CMake.
Without explicitely linking statically libmisc and libc4script,
we have the following link issue:

While at it, build libopenclonk statically since libopenclonk is not
installed by the CMake build system.

While amd64 always supports the SSE2 instruction set extension,
other architectures don't (including 32 bit x86). For the platforms
that don't, we'll use the reference C implementation by default, but
allow users to override it with the BLAKE2_USE_SSE2 option.
The crypto "library" only consists of a single function at the
moment because that's all that users have asked for so far. It is
also highly experimental. We will make an attempt to keep the public
interface (i.e. the interface provided by Library_Crypto.c) stable,
but it might still change if necessary. The internal interface
(provided via the global _Crypto proplist) is not for public
consumption and will probably change at some point.
GCC6 doesn't like getting some of its default include search paths
passed with the -isystem flag, and the devs seem unlikely to change
whatever they did back to before they broke it. Work around CMake
not dealing with it well either by figuring out the paths at
configure time and telling CMake about them so it can avoid adding
them superfluously.
In Tower of Despair, the scenario saves per-room progress in the
player files. Players win individual rooms, but never the whole
scenario. Consequently, they currently have to give up to make sure
they don't lose their progress. This is not intuitive at all. With the
new flag enabled, players will be saved even if the scenario is aborted.
