For gettimeofday, -ffixed-r30 was passed to work around a bug in Go

more bugs. So remove -ffixed-r30 for getrandom.
Strangely, I am _unable to_ make the Go code not crash with this patch
applied. I'm not quite sure what I'm doing wrong yet, or if this points
to another issue.
Do you mean that without this patch the Go code works and with this
patch it crashes ? That's strange taken into account that the chacha
function plays up with r30 regardless of this patch.
