* remove module flag from linking romio - it should be in the romio component

(which it is) and not romio itself
* Work around dark, evil linker voodoo that prevented building both shared
  and static libraries on OS X.  The global variables in ad_init.c were
  not initialized, and so were marked as tentative definitions, which caused
  much pain for the linker later on.  Initializing them makes them
  actual definitions and the problem goes away.  I hate linkers.
