The patch shouldn't affect sound, but since I can't prove I've ever
had working sound in 58-beta it has to remain a possibility.  The
intention is that the versions of graphite2 and harfbuzz already
pulled in by e.g. gtk3 can be used instead of the shipped (possibly
older) static versions provided by firefox.  As a consequence, the
system versions need to be at least the versions shipped in firefox
- the patches test that.

Finding details on the audio problem is hard - I posted last week, I
think (my mind is breaking up with Meltdown and Spectre) but both 57
and 58 seem to DLOPEN libpulse (or alsa, I suppose, if you use that)
from libxul.so - nothing links to it according to ldd, but strings
shows the reference.

Umm, my memory of this had been paged out.  Certainly at one time
there was a rust problem where those could not be found - but the
details should be in the book now.  /me looks at my script -

BINDGEN_CFLAGS

That problem has been fixed in firefox-58.

Iff anybody is using system png with ff58, I forgot to mention that
it needs the current version.  Probably also current nspr and/or
nss.
