If "-O2 -pipe -march=prescott" should not be used, then I suppose gnustep-gui 
should use

  libpng-config --I_opts

instead of

  libpng-config --cflags

when deciding what compiler flags to use.

gnustep-make does not filter compiler flags that you explicitly specify in the 
GNUmakefile;
they are used as they are.  That's by design; it would be frustrating to have 
gnustep-make
interfere with them.  So, if you add -O2 -march=prescott to 
ADDITIONAL_INCLUDE_DIRS
you are basically forcing these flags to always be used.  If you don't want 
that to happen,
well, don't add them there! ;-)

Thanks
