dmd -c -op -odbuild ../d01/fun.d
#will create  ./build, and write to ./d01/fun.o instead of ./build/d01/fun.o

dmd -c -op -odbuild /abspath/to/fun.d
#will not create ./build and not write any .o file, and not report any error
either

Without -op (flat hierarchy), dmd will also produce wrong results:
dmd -c fun.d util/fun.d 
#oops, fun.o overwritten 

ldc has a better way to handle the object flattening:
here, it'll create:
fun.o
util.fun.o
with no ambiguity (since '.' is not a valid character in a module anyways,
unlike '_', which was previously proposed).

We should have a flag to support the 'ldc' way.
translate paths a/b/c containing module foo.bar to:
build/a.b.c.o (choice 1, based on path given as input) or build/foo.bar.o
(based on module name)
For choice 1, we need to worry about the case of input files given as
'../foo/bar.d' but one way that would always work would be to 1st convert to
absolute paths every input file.

Note, this is a blocker for incremental compilation in '1 pass' (ie where we
don't compile each object file at a time but all in 1 go).
