Would it make to enforce the use of no-pie if the target is not
GNU/Linux emulation as it's done for other options in the configure
file since all target but GNU/Linux are bare metal. This issue may
affect other distributions or users building their own toolchain. When
experienced, it really feels like the smartcard was bricked and since
it's not a problem that easy to troubleshoot, it potentially lead to
some extra complaints from gnuk users.
