The Ghostcript project started to place their tarballs in two places
starting at 9.19 as explained in [1]. 9.18 version is considered old,
so including the 'old-gs-releases' in the URL.

- Previously, it did not build the whole local libpng
  source in ghostscript, only picked up specific files
  and compile them. But on ghostscript 9.18, when the
  arm's FPU has been set to NEON (-mfpu=neon * with GCC),
  the selected file "libpng/pngrutil.c" needs to link
  'png_init_filter_functions_neon' which should be
  compiled by a non-selected file "libpng/arm/arm_init.c".
  ...
  |./obj/pngrutil.o: In function `png_init_filter_functions':
  |armv7a-neon-poky-linux-gnueabi/ghostscript/9.18-r0/build/../
  ghostscript-9.18/libpng/pngrutil.c:3921: undefined reference to
  `png_init_filter_functions_neon'
  ...
  So do not compile local libpng source in ghostscript,
  use shared libpng to instead.

When using parallel make jobs, we need to be sure that
pnglibconf.h is created before we try to reference it,
so add a rule to png.mak.

* Update LICENSE's md5sum, the new version added a "of" in the file, the
  license is the same.
* Remove ghostscript-9.02-parallel-make.patch, it has 932 lines and
  modified 24 files, which is hard to maintain, and it can't be applied
  since the code has changed, and if we meet parallel issues again, we
  need fix it in other ways.
* Fix a build error of -Werror=return-type.

ghostscript application fails to fetch objarch.h file while building for armeb.
The fetch failure is due to absence of this file in the default set of
directories that the OpenEmbedded build system searches (i.e FILESPATH)
for patches and files. This patch adds the required objarch.h file for
armeb in one of the default locations where OpenEmbedded build system searches.
