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. finally use allsyms_nuttx to overwrite the already generated nuttx and regenerate binary outputs Signed-off-by: xuxin19 <xuxin19@xiaomi.com>

# 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
