New description:
If the environment variable {{{SAGE_TUNE_pari}}} is exported to "yes",
PARI will go through a tuning process to optimize the code for a
particular computer. This takes considerable time, so the default behavior
is not to tune PARI.
This is implemented in a PARI snapshot (see #9343), but is not documented.
In particular, it depends on #9343.

Comment(by leif):
If we support that at all, we should also emphasize that this is hardly
tested and (at least currently) fails on some (or a lot of?) machines...
