Remove "-frename-registers" option for sparc64 kernel builds. That

Browse Source 
was not present in what I originally tested when checking to see if
the kernel built/ran with the -O2 change.  Recent instability in
sparc64 kernel was tracked to this.  A reproducible kernel stack
traceback followed by hard hang during the call to msleep() at the
point the kernel waits 15 seconds for the SCSI bus to settle crept in
to recent kernel builds and it seems to go away with this patch.
