    + upstream fix for CVE-2021-40633 (bsc#1200551)
- Modified patches:
  * PIE.patch
  * reproducible.patch
    + rediff to changed context

- Define make_build for distributions which do not define them in
  system macros

- add reproducible.patch to avoid timestamp patching in the build
  section and allowing it to build with -Werror=date-time

- prep section should just extract and patch,
  further modifications have to be done in the build section

- Added patch:
  * PIE.patch
    + build path independent objects and inherit CFLAGS from the
    build system (bsc#1184123)

- Update to version 5.2.1
  * In gifbuild.c, avoid a core dump on no color map.
  * Restore inadvertently removed library version numbers in Makefile.
- Changes in version 5.2.0
  * The undocumented and deprecated GifQuantizeBuffer() entry point
    has been moved to the util library to reduce libgif size and attack
    surface. Applications needing this function are couraged to link the
    util library or make their own copy.
  * The following obsolete utility programs are no longer installed:
    gifecho, giffilter, gifinto, gifsponge. These were either installed in
    error or have been obsolesced by modern image-transformmation tools
    like ImageMagick convert. They may be removed entirely in a future
    release.

  * Address SF bug #134: Giflib fails to slurp significant number of gifs

  * Address SF bug #126: Cannot compile giflib using c89
