Bump page size to 64kB
We are seeing random failures with go programs on a 64kB page size ppc64 box.
It looks like garbage collection issues - sometimes we SEGV in timer code,
sometimes we SEGV in the code that wraps a kernel read syscall. If I prevent
the garbage collector from running, the programs work.
The libgo malloc hard codes the page size so I wrote a quick hack to bump this
(and a few other dependent variables). This makes the problem go away, but we
will need to come up with a better way to do this at runtime.
