commit: https://git.buildroot.net/buildroot/commit/?id=dba3bc3222e0bc3d6d1b881c107f693c47d0bc51
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.08.x

- Use tar.gz as SHA512SUMS does not contain the hash for tar.xz
- Fix CVE-2020-15900: A memory corruption issue was found in Artifex
  Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator
  can allow overriding of file access controls. The 'rsearch'
  calculation for the 'post' size resulted in a size that was too large,
  and could underflow to max uint32_t.

+Subject: [PATCH] configure.ac: fix cross-compilation
+
+Cross-compilation fails since version 9.53.0 and
+https://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=3ff82b33f24ed54c2d3bb88ec31da7d2f9fd2765
+
+Indeed, when x"$host" != x"$build", a recursive call to configure script
+(for auxiliary tools) is being made. In this call,
+--enable-auxtools_only and --without-libtiff are passed which will
+result in the following build failure because SHARE_LIBTIFF is not set
+and SHARE_LIBJPEG is set to 0:
+
+checking for local lcms2mt library source... configure: error: Mixing local libtiff with shared libjpeg not supported
+configure: error: Recursive call to configure script failed
