dev-lang/ada-bootstrap: add 14

This adds bootstrap tarballs for GNAT for the following platforms:
* aarch64-unknown-linux-gnu
* armv6j-softfp-linux-gnueabi
* armv6j-unknown-linux-gnueabihf
* armv7a-softfp-linux-gnueabi
* armv7a-unknown-linux-gnueabihf
* powerpc-unknown-linux-gnu
* powerpc64-unknown-linux-gnu
* powerpc64le-unknown-linux-gnu
* sparc64-unknown-linux-gnu

More are planned (like HPPA, but I had an issue there when using the
built tarball; I don't think the tarball was to blame, rather some
deeper issue needing investigation) but this feels like a decent set
to start with.

We should also of course build a fresh one for amd64 and also x86.

They were built using a script [0] using stage3-amd64-hardened-systemd-20241214T201851Z.tar.xz
with ::gentoo state around 16th November 2024 (I say "around" as I synced
in-between to get an eclass fix).

NOTE: I've only added ~arm64 for now as I've tested the binary there
to bootstrap GNAT natively. I'll add other keywords once tested.
