Glibc make tests failing on sh3

[Kristoffer Ericson]

Greetings,

(Bad at remembering emails/names so you might already know this)

You should give our userland a try at http://www.jlime.com. We currently use 
gcc 4.1.1 with glibc 2.5 (in the past used 2.3.6 -> 2.4). And it seems to 
run well. What kind of board are you using?

Best wishes
