# define_allsyms_link_target
#
# Description:
# Wrapper of cmake declaration of nuttx executable
# in order to implement ALLSYMS.
#
# When declaring the target to be `nuttx`,
# create an empty allsyms source file for it;
# When the target is declared as something else,
# the link behavior of the `nuttx` target is cloned
# and added to actually generate the allsyms file.
#
# Parameters:
# inter_target : declaration of target
# dep_target : targets which depends on
# allsyms_file : generated allsyms file name
# ~~~
