Fixes build error: undefined reference to `GifQuantizeBuffer'
that was most likely caused by giflib update in 3605f1285
ABI tracker didn't show removal of this symbol - I don't know,
perhaps we have different build setting, or something.
Here I found no NEWS, ABI tracker seems OK - only minor
incompatibilities in -private headers. Mono stuff builds now.
nix path-info -rSh on mono:
Before: /nix/store/p7zix8ypkqdwz86jvirzn0hmqhkbfhf7-mono-5.20.1.27 1.2G
After: /nix/store/zwg8d5m2d7hbi1ylh6rq00wyghyyzpsp-mono-5.20.1.27 881.3M
Mostly due to not dragging in cairo-dev, mesa-dev, etc.
Configure script complains, that unable to build gif loading support,
but it's a lie -- it builds against libgif 5, which have DGifOpenFile as
well.
