It also happened to me in a build directory whose path contains a
symbolic linked directory.  Make was confused to include the generated
makefile twice, which could be reached with 2 different pathnames.
After removing the symbolic linked directory, the generated makefile
can be reached with a single pathname, the make error went away.
