  Restore explicit export of ASTCFLAGS/ASTLDFLAGS and underscore-variants to sub-makes.
  
  During the recent Makefile improvements I made, it seemed the 'make' was
  automatically carrying down the ASTCFLAGS/ASTLDFLAGS settings to sub-makes,
  so I removed the explict export of them. However, there are some circumstances
  where make does this, and some where it does not, so I've brought them back
  to ensure they are always exported. I also removed an extraneous double setting
  of _ASTLDFLAGS on *BSD platforms.
