 As Thomas mentioned, for some reason you don't seem to be able to build a
shared library.

 To debug this, could you re-run (without cleaning) with BR2_DEBUG_WRAPPER=1 in
the environment? And also make it verbose, with V=1. And disable parallel build. So

BR2_DEBUG_WRAPPER=1 make V=1 BR2_JLEVEL=1

 If you haven't cleaned, the entire output is relevant (it would contain just
the commands that are run leading up to the failure).

 To make it smaller, you can run 'make savedefconfig' and include that in the mail.

 But anyway, the interesting bit is

BR2_RELRO_FULL=y

Full relro is currently broken. See the bug report [1] and the patches to fix it
[2].

 Arnout
