Subject: [PATCH 2/3] meson: build libsystemd-core via an intermediate static
 library

By itself, this is not useful. I'm making this a separate commit to
make debugging easier. It turns out that meson does static libraries
using references, so the "static library" a tiny stub stub that refers
to the object files on disk and this has negligible cost:

-rwxr-xr-x 1 zbyszek zbyszek 6.1M Jul  3 16:54 build/src/core/libsystemd-core-257.so

(cherry picked from commit d0689ee5fbfafa736e6eca89bc80cb2d372f2229)
