Slightly better is:

make -J N registration
make -J N lazutils
make -J N lcl

because the order as specified on the command-line is not guaranteed when you do parallel compilation.

Still, it feels strange to me that

make lcl

is not enough, but OK.

Makefile.compiled does not even come into play, see below.

That may not happen, because the sources will not be installed on the build machine.

The projects will be compiled with fpc only in a docker environment.
The devops people don't want another build tool. Only make.
(which is why I wanted to have make install working - but I had to resort to
using find and cp manually)

The goal is to have just fpc, its units and the LCL units in compiled form in the docker.
