Don't serialize build through psyntax-pp.scm

Browse source 
* 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.
