Uh, oh, for me it compiles just fine, using gcc 4.7.2.  What commands
did you try?  Which compiler version?  After unpacking the two
archives I did

  ln -s freetype-2.5.1 freetype2
  cd freetype-2.5.1
  make devel
  make
  cd ../ft2demos-2.5.1
  make

I'm not an expert in cross compiling, but relying on a
distribution-specific environment variable like $LIBPNG_CONFIG is
problematic.  Why not setting LIBPNG_CFLAGS and LIBPNG_LDFLAGS as
advertised on the command line?

  LIBPNG_CFLAGS=`$LIBPNG_CONFIG --cflags` \
  LIBPNG_LDFLAGS=`$LIBPNG_CONFIG --ldflags` \
  ./configure --host=... \
              --build=...

Behdad outlined a solution for pkg-config; see this thread:
