# 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).
