I run the command like this for c and c++ - /home/gcc/gcc-4.8.5/configure CC=/usr/bin/gcc --prefix=/home/gcc/gcc-4.8.5.install --build=powerpc64le-linux-gnu --host=powerpc64le-linux-gnu --target=powerpc64le-linux-gnu --enable-shared --enable-threads=posix --with-system-zlib --enable-__cxa_atexit --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,lto --enable-initfini-array --disable-libgcj --enable-gnu-indirect-function --with-long-double-128 --enable-secureplt --disable-multilib --with-cpu=power8 --with-tune=power8 I tried this command on a different system which has older version of gcc-4.8.3, I did not get any error while building, so I think building latest version gcc with older can work but reverse process will not work in some of the cases if I am right. But, actually I wanted to build this version of gcc(4.8.5) on my new machine which has 5.4 version.
