I think this patch is wrong, because if you build with the examples
disabled, the configure step fails with:
-- Detecting C compile features
-- Detecting C compile features - done
CMake Error at examples/CMakeLists.txt:14 (INSTALL):
install TARGETS given target "server" which does not exist in this
directory.

You need to add a comment:
comment "ubus needs a toolchain w/ dynamic library"

Why don't you just use the default installation logic, like is done for
the target installation ? Installing more than strictly needed to
staging is not a problem.
