make: Introduce compile time include/config.h generation
It's being reported that some systems (as Ubuntu 13.04) already
have struct tcp_repair_opt definition in their system headers.
| sk-tcp.c:25:8: error: redefinition of struct tcp_repair_opt
| sk-tcp.c:31:2: error: redeclaration of enumerator TCP_NO_QUEUE
So add a facility for compile time testing for reported entities
to be present on a system. For this we generate include/config.h
where all tested entries will lay and source code need to include
it only in places where really needed.
