# hdparm -tT /dev/sda /dev/mmcblk0
/dev/sda:
Timing cached reads: 512 MB in 2.00 seconds = 255.59 MB/sec
Timing buffered disk reads: 134 MB in 3.01 seconds = 44.49 MB/sec
/dev/mmcblk0:
Timing cached reads: 490 MB in 2.00 seconds = 244.49 MB/sec
Timing buffered disk reads: 36 MB in 3.09 seconds = 11.63 MB/sec
/dev/sda is a seagate momentus 5400.5 160GB laptop drive out of a broken
EEEpc 1008HA.
I will try giving the benchmark a try:

I guess that's quite a bit faster than your sheevaplug then. Especially
on floating point. No idea if the default gcc settings the makefile
used are even ideal.

So libtool seems to have built. I sent a patch to bug 632614 for it.
Now I can actually apt-get build-dep vim, so I guess libtool is rather
essential.
