powerpc: drop R_PPC_REL16 check

Current minimum support binutils (2.22) supports R_PPC_REL16 as default,
so no need to extra configure checks.

Checked on powerpc32-fpu.

--

	* sysdeps/powerpc/powerpc32/configure.ac: Remove R_PPC_REL16 check.
	* sysdeps/powerpc/powerpc32/configure: Regenerated.

--

If no one opposes, I will commit it today.
