Subject: powerpc/boot: Specify ABI v2 when building an LE boot wrapper
From: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx>
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")
