[PATCH, nios2] Fix linker provided _gp symbol

[Chung-Lin Tang]

Hi Sandra,
As I mentioned earlier, here's a fix for the nios2-linux emulation to
make _gp/gp hidden, analogous to the same issue Maciej fixed earlier for
MIPS:
http://sourceware.org/ml/binutils/2012-08/msg00064.html

Okay for trunk and 2.24 branch?

Thanks,
Chung-Lin

	* emulparams/nios2linux.sh (OTHER_GOT_SYMBOLS):
	Wrap _gp in HIDDEN(), and gp in PROVIDE_HIDDEN.
