Downgrade dist-powerpc-linux binutils to 2.30

With binutils 2.32, we were getting errors like this:

    relocation truncated to fit: R_PPC_PLTREL24 against symbol
        `__cxa_atexit@@GLIBC_2.1.3' defined in .plt section in
        /x-tools/powerpc-unknown-linux-gnu/powerpc-unknown-linux-gnu/sysroot/usr/lib/crt1.o

but it builds okay with binutils 2.30.
