That seems to work as well. Using "-Dpipelines=auto" and "Dipas" removed, I
get the following lines in log.do_configure:

This seems a good default for an aarch64 platform.

That's true as well (see above), but I still would like to disable unneeded,
unwanted IPAs or pipelines. If I read the meson code correctly an IPA is only
enabled if a corresponding pipeline is enabled as well, right?
