Well perhaps the ecls issue is resolved here. I rebuilt both ecls and  
maxima to use the default profile ldflags (LDFLAGS="-Wl,-O1  
-Wl,--as-needed") and

ecl-config --ldflags gives
  -L/usr/lib64/ -lecl -Wl,-O1 -Wl,--as-needed   -lpthread -ldl  -lm

ecls can now be configured and built with something like

LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--sort-common" emerge -1v --nodeps  
ecls

However, no luck with maxima. The above with ecls replaced with maxima  
now gives

   
\"/var/tmp/portage/sci-mathematics/maxima-5.20.1-r3/work/maxima-5.20.1/src/binary-ecl/init-cl.o\"  
\"-Wl,-O1 -Wl,--as-needed -Wl,--sort-common\"   -Wl,-O1  
-Wl,--as-needed  -lecl  -lgmp -lgc -lpthread -ldl  -lm ")

;;;  
/usr/lib/gcc/x86_64-pc-linux-gnu/4.4.3/../../../../x86_64-pc-linux-gnu/bin/ld:  
unrecognized option '--as-needed -Wl'
