Based on your description that there is no architectural issue with providing the probes on SPARC just a build environment issue.
Given what you described the way I would recommend that this case is changed to provide the functionality on both platforms. The project teams asks that due to the issue described that delivery on x86 be allowed before delivery on SPARC - this is really more of a C-Team issue but it helps to have had the ARC review. For the record I don't think Self Review is appropriate in any case where functionality delivers only on one of x86 or SPARC unless it is obvious that it can only apply to one or the other (eg it is a case about OBP or about hardware unique to x86). -- Darren J Moffat
