I can't build anything on ia64 with the new linker. Without
--as-needed, I got

./ld  -dynamic-linker /lib/ld-linux-ia64.so.2 -o build/foo
/usr/lib/crt1.o /usr/lib/crti.o ./crtbegin.o -L. -Lstage1
-L/usr/gcc-4.0/lib/gcc/ia64-unknown-linux-gnu/4.0.0

build/rtl.o build/read-rtl.o build/ggc-none.o build/min-insn-modes.o
build/errors.o ../build-ia64-unknown-linux-gnu/libiberty/libiberty.a
-lgcc  -lgcc_s -lunwind  -lc -lgcc  -lgcc_s -lunwind  ./crtend.o
/usr/lib/crtn.o
./ld: BFD 2.15.94.0.3 20050201 assertion fail

./ld: BFD 2.15.94.0.3 20050201 assertion fail
