[pbs-devel] [PATCH v2 proxmox-backup 3/5] Makefile: switch path based on build mode and target

[Christian Ebner]

Define variables for the compile path and target and use these
instead of hard-coding the path. Allows to easily switch between
debug and release mode for compilation.

Also, place the libsystemd stub into its own subdirectory for cleaner
separation from the compiled artifacts.

changes since version 1:
- use dedicated variables for compile dir and build target
- place libsystemd stub into dedicated directory for clear separation
