at 3.1.13: get 'at' depends on 'flex-native' explicitly
'at' needs flex to generate source file lex.yy.c, but it doesn't
depend on flex-native directly; This maybe cause a do_compile
failure if flex-native is not built or included in project.
Error message is:
error: lex.yy.c: No such file or directory
Get 'at' depends on flex-native to fix this potential issue.
