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