Bug description:
This is an Ubuntu-power-systems 22.04 LTS feature bug to track
changing the gcc configure options from --with-cpu=power8 to --with-
cpu=power9.
Prerequisites for this bug include power9 builder hardware in
Canonical datacenter.
I'm still learning my way around Debian/Ubuntu source so go easy on me
if this isn't the correct branch:
https://salsa.debian.org/toolchain-
team/gcc/-/blob/gcc-10-debian/debian/rules2#L394
But we'll want to add some logic around line 394 to add --with-
cpu=power9 for 22.04 and possibly --with-tune=? but I'll reverse
mirror this bug and verify with our IBM Power toolchain architect.
