That was never ever supported. In VLC 1.0 and earlier, the plugin cache could
only be generated by running VLC and was stored in the per-user cache
directory. In VLC 1.1, the plugin cache depended on the architecture and CPU
model and could only be generated by running native code from the final
installation path. In VLC 1.2, only the CPU model variability was removed.

This is just plain stupid. The earliest correct/supported time the cache can
be built is after VLC is installed. At that point, you do know the _one_
architecture so the issue is moot. The plugin cache content depends on the
installation prefix. If you (try to) do generate the cache from the build
host, VLC will ignore the content, and regenerate it at the first run.
If the user cannot write the cache, then you might as well disable the plugins
cache; it will work just as well (even slightly faster).
If the user can write the cache, then you might as well ignore the
(non-)problem, and let the cache be generated at first run like before.
