OK in the end all the slow download problems I met while testing oe-core
& qemuarm from scratch were due to a problem on the server hosting
yocto's git and mirror services (so setting PREMIRROR to use
yocto's mirror didn't improve the situation).
Now that this problem is fixed on the yocto server, the time to download
linux-yocto kernel went from 90-120 minutes down to 20-30 minutes
which seems more reasonnable !
So there was really a problem but I was not looking in the right
direction to fix it :-(
