Patchwork [1/1] at 3.1.13: get 'at' depends on 'flex-native' explicitly

From: Wenzong Fan <wenzong.fan@windriver.com>

'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.

[YOCTO #2919]

Does it need flex for the target as well, or was it a case of "flex" being added 
instead of "flex-native" by mistake?

Cheers,

Ok, I understand the flex-native dependency, that makes sense, but I 
wonder why there was a dependency on flex originally?  Is that actually 
needed?

Sau!

Yes, it is needed.

I removed 'flex' from DEPENDS, the build failed with:
---------------------------

--sysroot=/buildarea/wfan/at/tmp/sysroots/qemux86 -I. -O2 -pipe -g
