llvm: Build all targets

The [/pkg-package builds all targets][1], so do the same here.

Currently:

    $ clang --version
    clang version 14.0.4
    Target: x86_64-unknown-linux-gnu
    Thread model: posix
    InstalledDir: /usr/bin
    $ clang --print-targets
      Registered Targets:
        amdgcn - AMD GCN GPUs
        bpf    - BPF (host endian)
        bpfeb  - BPF (big endian)
        bpfel  - BPF (little endian)
        r600   - AMD GPUs HD2XXX-HD6XXX
        x86    - 32-bit X86: Pentium-Pro and above
        x86-64 - 64-bit X86: EM64T and AMD64

After enabling all targets (and rebuilding/updating clang in the
follow-up commit):

    $ clang --version
    clang version 14.0.6
    Target: x86_64-unknown-linux-gnu
    Thread model: posix
    InstalledDir: /usr/bin
    pmenzel@invidia:~$ clang --print-targets

This increases the (compressed) package archive size by 24 MB.
