    Don't serialize build through psyntax-pp.scm
    
    * bootstrap/Makefile.am: Don't serialize the build through
      psyntax-pp.scm.  On a multicore make, this will result in higher total
      CPU time as multiple processes use an interpreted expander, but lower
      total build time, as all processes will take approximately the same
      time to load and run the compiler.
