And dlerror returns dlfcn_error if statically linked:
static char dlfcn_error[] = "Service unavailable";

Hence the thing is already correct. Perhaps the message could
be improved? "dlopen() is not available in statically linked binaries".

Or just fail with an #error when trying to build statically?
