without specyfing --enable-parallel you get the same, since it is the default when a 
multicore machine is detected by configure. If you want to compile serially you need to 
add --disable-parallel (or similar, see ./configure --help)

So the problem arised after reinstalling the OS, if I understand well? If so, most 
probably the MPI implementation has not been installed correctly. Have you run some tests 
to understand if the parallel compilers work properly before trying to install QE?
Are you sure that you have write access to /tmp and local directories?
