Didn't fix related bogotification from moving the definitions of
DPADD and LDADD to here. Setting these variables in a top-level
directory gives bogus dependencies in library subdirectories.
E.g., there is a dependency on `foo.so..' where the double dots
separate null shared library version numbers.
Set BINDIR properly by inheriting it from ../Makefile.inc.
