The following files are now provided by Newlib:
* arpa/inet.h
* net/if.h
* netinet/in.h
* netinet/tcp.h
* sys/socket.h
* sys/uio.h
* sys/un.h
The <sys/param.h> and <sys/cpuset.h> are now compatible enough to be
used directly.
Update #2833.
- Update the file builder generator to handle generator specific cflags and
includes. The tcpdump and libpcap have localised headers and need specific
headers paths to see them. There are also module specific flags and these
need to be passed to the lex and yacc generators.
- Add the tcpdump support.
