package/directfb: disable for static builds
DirectFB is written in C++, but can be linked to by a C library or
program.
When doing shared link, this is fine because the linker gets help from
the DT_NEEDED flags and knows what libraries to pull in during the link.
However, during a static link, the linker does not get such help.
Properly fixing this would require that there is support in pkg-config
and autotools to specify that the C++ runtime must be linked. Alas there
is no sush support. The only option is to add -lstdc++ to the
Libs.Private field in directfb.pc. But this is not upstreamable, because
there are other C++ runtimes in the wild (e.g. -lc++ from llvm/clang).
However, DirectFB in a static scenario is probably not a very common
scenario.
Disable DirectFB for static builds.
