Will this problem disappear if end programs will pass --as-needed flag
to the ld command line?

Some of it is also pkg-config's fault. For example, anyone using
pkg-config with gtk+2 gets the following:

# pkg-config --libs gtk+-2.0
-L/usr/X11R6/lib -lgtk-x11-2.0 -lgdk-x11-2.0 -lXrandr -lXi -lXinerama
-lXext -latk-1.0 -lgdk_pixbuf-2.0 -lm -lpangocairo-1.0 -lfontconfig
-lXcursor -lpango-1.0 -lcairo -lXrender -lX11 -lgobject-2.0
-lgmodule-2.0 -ldl -lglib-2.0

Which is all crap. Yes, this is the list you need for static, but
pkg-config is recursing through modules even for dynamic linking which
is wrong. Now either pkg-config of the gtk+2 pc file needs to be
fixed, then you can start recompiling all the affected programs...

Some of the discussion in bug #340904 is relevent here.
