Something seems to have gone wrong in our rebuild and sync of pulseaudio
with alpine upstream. And user feedback points that building armv7 devices
with LTO is actually broken in our builders. In alpine, they enabled lto
in pulseaudio very long ago (f46174365b219fe431890df3df7e7dc488c9451e 08-09-22)
and nobody as complained so far. Since it's not really a phone-specific package,
one would hope that more people upstream would have noticed if it were broken
there. Since nobody has, we assume this is a downstream problem, and just
unconditionally disable lto in our build. We hope this will be just a temporary
workaround, until the patches that prompted the fork are no longer needed, and
we can simply use upstream pulseaudio, that shouldn't be broken.
