[libmd PATCH] Fix out of source build

[Michael Haubenwallner]

Adding local-link.h as private header file requires $(srcdir) on
AM_CPPFLAGS to be found by generated sources when builddir != srcdir.

Do not use libmd.sym from $(srcdir), as it is a generated file.
Also, do depend on libmd.sym only if it really is used.
