Comment(by malb):
* there's an optional parameter {{{--with-cachesize}}} for M4RI's
configure which allows to specify L1 and L2.
* However, this is not exported to Sage, i.e. M4RI_EXTRA_OPTS does not
exist yet.
* M4RIE does not re-tune any more but re-uses the data from M4RI.
* In my experience (on i7s for example) tuning is much better than using
the data reported by the CPU. That is, if one trusts L1 and L2 as reported
by the CPU (which are correct) the code is much slower than tuning which
essentially uses L3 instead of L2.
