I noticed that this error only happens in a modifed tree with the libgo
multilib check patch

    http://gcc.gnu.org/ml/gcc-patches/2011-04/msg00247.html

Investigation showed that _testmain.go differs between the two trees:

It turns out that this was caused by passing $GOCFLAGS in CHECK (GC),
which was meant to pass the multilib flags, but isn't necessary since
those are included in $GOC.

But unfortunately the default (-g -O2) changes the outcome of this and a
couple of others tests.  I don't think the tests should be so fragile.
