Hi.
No need to CC Mike or the readline list, as far as they're concerned
this was already fixed with the patches upstream.
Well, it's easy, fetch the patch:

$ wget
"http://git.buildroot.net/buildroot/patch/?id=b817e8c58117402561a61c0d749337f415c9c985"
-O readline.patch

Apply the patch:

buildroot-2015.02 $ patch -p1 <readline.patch

And yes, the patches need a little tweak to apply cleanly (the patch
prefixing is done in a somewhat odd way), but i've handled that in the
patch i've sent for buildroot inclusion.
Regards.
