- stop building ff/tb/sm with systemwide cairo, it differs too much from
the bundled cairo and brings us too many issues (font weirdness,
crashes on i386 when links are dnd'ed, maybe system slowness when
displaying huge images, and others i dont remember..). Anyway, this is
not really "supported" upstream. To be revisited once mozilla updates to
cairo 1.12.x, if ever (#739096).
- move comment about system-jpeg, krb5 WANTLIB, and post-extract target
about sydneyaudio sndio backend when they belong (ie in the 'old' users
case).
