# 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).
