NACK for the CONFIG_USE_STRIP change. Most dynamic linking (e.g. via
dlopen) works just fine. If python has an issue there, we should fix
that, or use strip instead of sstrip only for pyusb and similar things.

As for using GCC on OpenWrt, I think that's exotic enough to not be a
reason to push a size increase onto everybody else.

Regarding debugging with gdb, I use the gdbserver + cross gdb on the
host, and it tends to work just fine even with sstrip.
