gdk-pixbuf is based on plugins (modules in gdk-pixbuf parlance) that are
provided either by the gdk-pixbuf package itself, or be installed by
third-party packages, like librsvg. At runtime, those plugins get loaded
by helper function in the gdk-pixbuf library.
The location where to find those modules is currently hard-coded at
build time, to the location where gdb-pixbuf is installed.. This means
that host-packages that install image-conversion utilities will try to
look in the path where gdk-pixbuf was installed.
With per-package directories, this fails to find any module that was
installed bu a third-party package. For example, the module for loading
an SVG provided by librsvg, so it is not present in the PPD of
gdk-pixbuf, and thus loading an SVG (e.g. to convert it to another
format, like adwaita-icon-theme does) will fail with:
Can't load file: Unrecognized image file format
However, gdk-pixbuf can be configured so as to look for the modules
relative to where the program is run from, rather than hard-coding the
location at build time. This is exactly what we need in the PPD case
Additionally, even without PPD, this would fail in a similar manner in
the SDK, as that can be relocated too.
So we unconditionally enable the relocatable option, but only for the
host variant (there is no reason to enable it for the target, as it is
not going to be relocated).
