Clarify variables flow.

Prevent build-doc to compile the library again into .build/obj,
because without -subdir .build/obj/TARGET/MODE/static is not seen.

No need to recompute SDIR in regtests/Makefile, it is set in makefile.setup.

Remove duplicate PRJ_BUILD in ALL_OPTIONS.

Avoid undefined VERSION in templates_parser.gpr when building examples.
