New description:
This perhaps just gets a meta-ticket to collect various additions (or
changes), to be discussed and implemented on their own tickets.
There are a few things I would like to have a `make` target for, partially
just for convenience (at the moment random choice / incomplete, random
order):
* `build-check`, perhaps also `all-check`, as an "alias" for
{{{
#!sh
env SAGE_CHECK=yes make build
}}}
* `build-parallel` or something like that to build Sage in parallel with
a default number of jobs (preferably the number of cores or hardware
threads), or at least (currently just) setting
`SAGE_PARALLEL_SPKG_BUILD=yes` and doing the usual thing
* `build-sequential` in case we one day default to a parallel build
* similar things for `doc` (see below) and `all`
