Fix tty driver build on SPARC by not using __exitdata.
It appears that SPARC does not support section .exit.data.
Fixes these build errors:
`.exit.data' referenced in section `.exit.text' of drivers/tty/n_hdlc.o: defined in discarded section `.exit.data' of drivers/tty/n_hdlc.o
`.exit.data' referenced in section `.exit.text' of drivers/tty/n_hdlc.o: defined in discarded section `.exit.data' of drivers/tty/n_hdlc.o

Wow. That commit is from 2.5 years ago. Is the SPARC port still alive?

Shouldn't this be somewhere else? Any other driver wanting to use
__exitdata would need a similar patch. This feels like it should be
handled where __exitdata is normally defined?

Yes, it is. No idea why we didn't run into this. I assume it affects certain
configurations only. On Debian, we are always compiling and running the
latest kernel versions on sparc64.

Yeah, that's what I thought. I also didn't hit it 2.5 years ago when I
did multi-architecture build validation of these changes. :P
Randy you've found a nice corner case! :)
