You could use a recent version of hmake, with the -d OUTPUT_DIR
option.  This will place .o files in directories corresponding to
their hierarchical names.

e.g.
    hmake -ghc Main -i. -d OUTPUT_DIR
generates
    OUTPUT_DIR/Main.o
    OUTPUT_DIR/Bar/Module.o
    OUTPUT_DIR/Foo/Module.o
and links them to a final executable ./Main.
