    operations, tools: module.c not properly generated in VPATH builds.
    
    None of the core, common and generated operations were registered inside
    respective `common.c` when `gen-loader.sh` was not run from inside the
    directory with all the source files. Such build case typically happens
    on VPATH builds.
