I will be going through the packages in the next days, for now a couple
of notes on the ones you mentioned already, below.

I fixed this locally using:

  MUSEPACK_NINJA_OPTS = -j1

Sadly, switching to Ninja does not fix parallel builds for this package.

Replacing with the following works, because the CMake Ninja generator also
produces top-level phony targets:

  HOST_MARIADB_NINJA_OPTS = import_executables

Both these tweaks (and likely a bunch more) will be part of v2 of the patch
set :)
