Subject: merge new_loader_completion branch, including (at least):   -
 restructured build tree and makefiles to eliminate recursion problems   -
 support for embedded modules   - support for static builds   - simpler
 cross-compilation support   - simpler module/loader interface (no exported
 symbols)
