Alternative solutions like adding an explicit `--libdir=$BINUTILS_INSTALL_DIR/lib` in the binutils `configure` setup was tested, but this option was ignored by the libibrerty build on the binutils versions I've tried.

libiberty's `make install` always uses `gcc -print-multi-os-directory` to determine the target directory name. We can't change it.
The patch looks good to me.
