Yes. What's your configure command? You probably need at least --with-newlib.

I think my last successful msp430 build was using:

.../gcc/configure --target=msp430-elf --prefix=$HOME/gcc/msp430-elf
--disable-libcc1 --disable-libgomp --disable-libitm --disable-libssp
--disable-libvtv --disable-nls --with-system-zlib
target_alias=msp430-elf --disable-libstdcxx-pch
--disable-full-memory-range --with-newlib --enable-libstdcxx
--enable-languages=c,c++

With the cross binutils already installed to $PREFIX/gcc/msp430-elf
