Presumably, you are using an x86_64 computer, and the successful build
of gst-plugins-base is for an x86_64-linux system. However, the wine
package and its dependency graph is always built as 32-bit software,
regardless of the underlying architecture:

From gnu/packages/wine.scm:
------
    (arguments
     `(;; Force a 32-bit build targeting a similar architecture, i.e.:
       ;; armhf for armhf/aarch64, i686 for i686/x86_64.
       #:system ,@(match (%current-system)
                    ((or "armhf-linux" "aarch64-linux")
                     `("armhf-linux"))
                    (_  
                     `("i686-linux")))
------

And the test failure in the 32-bit build of gst-plugins base was
previously discussed on help-guix (no bug report):
