New description:

 The patches on this ticket remove necessity to set the environment
 variable `SAGE_PARALLEL_SPKG_BUILD` to turn parallel spkg building on.
 Thus it will be on by default, but note that "parallel spkg building" only
 has an effect if `MAKE` is set to, for example, "make -j16".

 In the current implementation, parallel building can be disabled by either
 setting the variable to "no" or by running "make build-serial".

 This change was discussed in [https://groups.google.com/d/topic/sage-
 devel/FW5sP5NPeLs/discussion sage-devel].

 Apply:

  - [attachment:trac_11959-sage.v2.patch] to the Sage library
  - [attachment:trac_11959-root.v2.patch] to the root repository
