Bug#877507: ppx-core FTBFS: E: Cannot find external tool 'ocamlbuild'

[Ralf Treinen]

This can easily be fixed by adding ocamlbuild to the build-dependencies.
But then:

File "src/gen/common.ml", line 73, characters 24-34:
Error: This expression has type Types.constructor_arguments
   but an expression was expected of type Types.type_expr list
Command exited with code 2.
