 #   (2) VXWORKS_BASE_EM_FILE set the hook's LDEMUL_FOO variable to
 #       gld${EMULATION_NAME}_foo.  This means that the file has
 #       replaced elf32.em's default definition, so we simply #define
 #       the current value of LDEMUL_FOO to vxworks_foo.
 #
 #   (3) VXWORKS_BASE_EM_FILE set the hook's LDEMUL_FOO variable to
 #       something other than gld${EMULATION_NAME}_foo.  We handle
 #       this case in the same way as (1).
