Hi,
We're considering bringing up a ppc64 port of the Ubuntu server, and it
appears to be best to build it with -O3 rather than -O2. (I realise
that this would be unusual in Debian and that there are more obstacles
to this than just dpkg-buildflags, and I'd like to do this differently
eventually, but this is where we are at the moment.) Could you please
apply this patch to Dpkg::Vendor::Ubuntu to change our default compiler
flags for that architecture?
* Set Ubuntu ppc64 optimisation to -O3.
