crude workaround for a DIFFERENT PROBLEM: ustat missing

while trying to build gcc 4.8.0 on SLES 9.4 I ran into a problem with struct
ustat and this patch let me work around it. It's not a fix, just ignores the
problem, but it might give you guys (who have a much better knowledge of the go
support) a hint where to look.

Supporting older kernel than 3.0 is going to be hard.  Closing as won't fix.
