But who will run qemu-iotests on Wine on Solaris? Running it on Wine on
Linux is already crazy enough. IIUC the sed call won't break anything,
it may just not work and won't strip out the carriage returns. Well, bad
luck, try a sane setup instead.

(I would see it different if this was ./configure, but it is a test case
output filter)
