I'm maintainer of whole meta-oe, but don't know much about libedit (I
was probably just fixing some issue detected in my verification builds).

Sorry I'm quite busy right now, I can only confirm that I've built
libedit few times last week for arm/x86/x86-64 architectures and it
doesn't fail here (but my jenkins builds are using pretty default values
not like poky-tiny or like you said "shrinked down version of poky distro".

Asking in openembedded-devel ML is good start and from your description
(without looking at actual libedit code) it really looks like bug in
upstream, so after checking with latest libedit you should report it
there as well.

I've added oe-devel to CC.
