# Hook in our routines above.  There are three possibilities:

#

#   (1) VXWORKS_BASE_EM_FILE did not set the hook's LDEMUL_FOO variable.

#       We want to define LDEMUL_FOO to vxworks_foo in that case,

#

#   (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).
