To add a little data here, the default Cirrus-CI build (using the
llvm13 package, and not building a target toolchain) took, in a recent
run of mine:

42:32 total
21:30 buildworld + kernel
(the non-build time is spent provisioning the VM, `git clone`,
packaging world, and running a test in QEMU)

A run that included two Clang builds (bootstrap and target compilers) took:
1:46:49 total
1:23:47 buildworld + kernel
