Hello,

I think it would need to be 4-state,  [dlopen / link / yes (which
prefers dlopen but does not require it) / no].

Alternatively a global setting could be used.

AC_ARG_ENABLE ([dlopen],
  [AS_HELP_STRING([--disable-dlopen],
    [link against instead of dlopening some helper libraries]),
  [ac_dlopen=$withval], [ac_dlopen=no])

I do not have a strong preference. I can try to come up with a patch
once a choice has been made.
