powerpc/boot: Specify ABI v2 when building an LE boot wrapper
The kernel does it, not the boot wrapper, which breaks with some cross compilers that still default to ABI v1. Fixes: 147c05168fc8 ("powerpc/boot: Add support for 64bit little endian wrapper") Cc: stable@vger.kernel.org # v3.16+ Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
