I'm going to simply drop the remaining USE=static's where appropriate,
if upstreams choice is to disable static libraries, and we'll see even
later what to do about those that don't default to not building static
libraries. For now I stumbled on just gtk-engines.

That is, some GNOME packages make it their own business to override the
automake default of building both - they call AM_DISABLE_STATIC.
So for those I'll just drop any --{enable,disable}-static (as I notice)
and honor upstreams choice in not building static libraries. This also
means nothing uses or needs the static libraries because all GNOME
tinderboxes and jhbuild based development machines would scream in agony
if it broke anything.

I know of absolutely no GNOME package that needs its static libraries
installed. Only exception is glib, but that is a lower level library,
not a GNOME one - there we explicitly enable it for syslog-ng possible
use primarily. And for glib I'm quite cool in enabling it always, as my
take on glib is that it's a standard C library that makes C actually
usable and powerful, just as libstdc++ makes C++ more powerful, and
should be universally available to all. Though an alternative would be
to install it in /lib, so that boot tools can use it and not need to
link statically - having syslog-ng in mind primarily.

And now I'm reiterating it again the first time since 3 months.

And probably G2CONF too, but we like to use that for ebuild use only -
we aren't sure we have G2CONF="${G2CONF} foo" everywhere, etc.
