- Explicitly moving the files breaks them, because the wrappers
reference the files by absolute path. Also this automatically
moves the manpages to $dev as well.
- Need to explicitly set --exec-prefix since the pkgconfig file has
`toolsdir=${exec_prefix}/bin`, breaking totem:

While at it, enable parallel build.
The $lib output refers to the terminfo database in $out, which is about
10x larger than the ncurses shared library. Splitting these outputs
saves a small amount of space for any derivations that use the terminfo
database but not the ncurses library, but we do not have evidence that
any such exist.
(And while at it, gst-vaapi 0.6.0 -> 0.6.1.)
* gst-editing-services grew additional build time dependencies, flex and
perl.
* gst-libav switched from libav to ffmpeg as "libav" provider, see
http://gstreamer.freedesktop.org/releases/1.6/.
Without using ffmpeg, one may hit issues such as this (which I
initially did):
(gst-plugin-scanner:19751): GStreamer-WARNING **: Failed to load plugin '/nix/store/0wgpq2yx9wrkp2mh4rn1c7zbiq2bqa2l-gst-libav-1.6.1/lib/gstreamer-1.0/libgstlibav.so':

This seems to have been confusing people, using both xlibs and xorg, etc.
- Avoided renaming local (and different) xlibs binding in gcc*.
- Fixed cases where both xorg and xlibs were used.
Hopefully everything still works as before.
It was really ugly that `xlibs.xlibs` meant something else than `xlibs`,
especially when using `with xlibs`, such as in wine.
Also, now `xlibs` is the same as `xorg`.
So that the tools become useable. The cool thing about wrapping them
like this (looping over $NIX_PROFILES) is that they will work on
non-NixOS systems too, given that $NIX_PROFILES is set correctly.
If you want the old (pure?) behaviour, just run gst-launch etc. with
empty $NIX_PROFILES.
