[PATCH] PowerPC: Guard CALL_ELF check for ppc64 only in link.h

[Adhemerval Zanella]

This patch fixes undef compiler warnings for _CALL_ELF, since it is
defined only for powerpc64.

Checked on powerpc32-fpu, ok to apply?

	* sysdeps/powerpc/bits/link.h [_CALL_ELF]: Guard check for
	__ELF_NATIVE_CLASS equal to 64.
