## OpenKal 0.25 dependency group

Runtime 0.20.1 builds for FreeBSD above openkal-musl (`x86_64-freebsd-musl`,
`aarch64-freebsd-musl`): the selection of compiler-rt is Linux's and the ok
image's, and `clear_cache.c` is kept, since nothing beneath a program of those
rows supplies `__clear_cache`. The rows need openkal-musl 0.29.1, whose
FreeBSD port offers `elf_aux_info`, which compiler-rt's aarch64 `cpu_model`
calls there. The OpenKal conformance suite built so holds every observation in
a FreeBSD virtual machine.

Runtime 0.20.0 is built over openkal-musl `^0.29.0` and the OpenKal 0.25
implementations beneath it (Linux 0.26, macOS 0.23, Windows 0.21, OpenSBI 0.9).
The C++ runtime surface and the allocator selection are unchanged. Through the C
