dpkg-buildflags: use CFLAGS="-g -O3" for building ppc64 packages on Ubuntu
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.)
