powerpc/boot: Specify ABI v2 when building an LE boot wrapper
commit 655471f54c2e395ba29ae4156ba0f49928177cc1 upstream. 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") Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
