Its a mistake. Go ahead and change it. I never noticed it probably because you
can't compile C++ files
for rtlinux (in fact most of our .c files can't be compiled for rtlinux). It
should actually  only copy  a fairly small number of .c files over. 
This is why there are numerous

ifeq (rtlinux, $findstring(rtlinux, $(PLAT)))

in the makefiles that prevent these files from being copied or compiled for
rtlinux.

Again you can't really compile tcpproxy.cc for rtlinux even if you have the
right header files.
(Well maybe you can compile it but the program won't run in real-time so there
isn't much point.)

There should be a  ifeq in the top-level makefile to prevent the make from even
trying to compile 
tcpproxy for rtlinux.
