Rodrigo Rebello 7a960de66f chocolate-doom: add patch to fix static linking
This commit adds a backported upstream patch which modifies the
configure script so that it uses pkg-config to detect libraries and
their static linking dependencies.

It also adds host-pkgconf as a dependency and removes the SDL static
linking workaround from chocolate-doom.mk as it's no longer necessary.

Fixes:

Subject: [PATCH] configure: Switch to pkg-config macros.
All dependency libraries install pkg-config .pc files nowadays, which
makes the process of looking them up a lot simpler. Get rid of the SDL
workaround macro as it's not needed.
[Backported from upstream commit 3163bf87d7b955d08dedd5ebaccb1b2a86ffdcb9.
Fixes static linking issues with SDL_mixer.]
