Interesting. Invoking

LDFLAGS="-Wl,-01 -Wl,--sort-common -Wl,--as-needed" emerge -1v --nodeps maxima

I get,

32bit chroot:

"/var/tmp/portage/sci-mathematics/maxima-5.20.1-r3/work/maxima-5.20.1/src/binary-ecl/maxima"

... a very long line ...

"-Wl,-01 -Wl,--sort-common -Wl,--as-needed"   -Wl,-O1  -lecl  -lgmp -lgc -ldl   
-lm
usr/lib/gcc/i686-pc-linux-gnu/4.4.3/../../../../i686-pc-linux-gnu/bin/ld:  
unrecognized option '-01 -Wl'

----------------------
amd64:

"/var/tmp/portage/sci-mathematics/maxima-5.20.1-r3/work/maxima-5.20.1/src/binary-ecl/maxima"

... a very long line ...

"-Wl,-01 -Wl,--sort-common -Wl,--as-needed"   -Wl,-O1  -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 '-01 -Wl'

So in both cases -Wl,-O1 is appended to the LDFLAGS passed to emerge.
