    maintainer-scripts/gcc_release: compress xz in parallel
    
    1. This should speed up decompression for folks, as parallel xz
       creates a different archive which can be decompressed in parallel.
    
       Note that this different method is enabled by default in a new
       xz release coming shortly anyway (>= 5.3.3_alpha1).
    
       I build GCC regularly from the weekly snapshots
       and so the decompression time adds up.
    
    2. It should speed up compression on the webserver a bit.
    
       Note that -T0 won't be the default in the new xz release,
       only the parallel compression mode (which enables parallel
       decompression).
    
       -T0 detects the number of cores available.
    
       So, if a different number of threads is preferred, it's fine
       to set e.g. -T2, etc.

            * gcc_release (XZ): Add -T0.
