Bug#35694: dlerror declaration is missing const

[Kevin Dalley <kevin@seti.org>]

Package: libc6-dev
Version: 2.1.1-0.1

/usr/include/dlfcn.h has the following declaration of dlerror:

extern char *dlerror __P ((void));

However, the man page for dlerror returns a const, which I suspect is
correct:

const char *dlerror(void);

Either libc6-dev or manpages-dev have an error.
