After making `ffmpeg` point to the latest `ffmpeg_4`, all packages that
used `ffmpeg` without requiring a specific version now use ffmpeg_3
explicitly so they shouldn't change.

Since years I'm not maintaining anything of the list below other
than some updates when I needed them for some reason. Other people
is doing that maintenance on my behalf so I better take me out but
for very few packages. Finally!
OpenCV's CMakeFile will use libraries in /lib and /lib64 if it can
find libraries from those paths. However, it causes
build failure because nix detects impure paths being used.
It used to contain:
````
includedir_old=${prefix}/include/opencv
includedir_new=${prefix}/include
Cflags: -I${includedir_old} -I${includedir_new}
````
Should fix build of 'seeks' and some others.
The following parameters are now available:
* hardeningDisable
To disable specific hardening flags
* hardeningEnable
To enable specific hardening flags
Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.
cc-wrapper supports the following flags:
* fortify
* stackprotector
* pie (disabled by default)
* pic
* strictoverflow
* format
* relro
* bindnow
In particular, this prevents KDE from pulling in gfortran, numpy and
atlas. We don't want anything important depending on atlas because it
has a crazy non-deterministic build system.

something'.
It should not link at least for '-x c-header' and '-x c++-header', and maybe
link for '-x c' or '-x c++', but we expect noone will be linking using these
later strings.
Adding opencv, which required '-x c-header' working, and that's why I have
updated gcc wrapper.
