Subject: [PATCH] packaging: Allow building QEMU for CC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We're adding a new target for building QEMU for CC, but it's important
to note that the only difference between this one and the "vanilla"
build is the installation path.

The reason we're taking this approach is because the first release
target for CC doesn't include TEE support.

We had to also include a new builder for QEMU, a specific one for CC, as
for now that's the easiest way to override the prefix in a way that
we'll be easily able to expand the script to support TEE capable builds
in the very near future.

Fixes: #4568
