-odir option changes .o and .hi names of main source file to Main.hi/o

One-liner illustrating problem:

    cd /tmp/ &&
    mkdir __tmp_ghc_test &&
    cd __tmp_ghc_test &&
    echo 'main = print 1' > foo.hs && ghc --make foo.hs -odir . &&
        rm -f * &&
    echo 'main = print 1' > foo.hs && ghc --make foo.hs

The output is:

[1 of 1] Compiling Main             ( foo.hs, Main.o )
Linking foo ...
[1 of 1] Compiling Main             ( foo.hs, foo.o )
Linking foo ...

In the first invocation we have got foo.hi/.o, but in the second Main.hi/.o.

It causes problems when user wants to write her custom Makefiles with predictable interface file names.

Or just wants to build two programs in one dir:

ghc --make foo.hs -odir .
ghc --make bar.hs -odir .

Which .o/.hi files will be used in the second case?

Thanks!
