Pull request description:

  Switch to using [GCC `12.3.0`](https://gcc.gnu.org/gcc-12/) to build release binaries.

  Temporarily disables the `powerpc64le-linux-gnu` target due to non-determinism issues when building across `aarch64` and `x86_64`. Trying to fix the non-determinism was going to require trying to selectively disable optimization flags, which is already not ideal (and didn't fix all issues), and the migration to GCC 12 as our release compiler is now the blocker for multiple other (c++20 and similar) changes, so leaving this blocked on the `powerpc64le` binaries does not seem like a good tradeoff.
