Ok, so this is what I do (on a pristine tree, after cloning the
buildroot and the packages feed):

First, I change the CPU subtype to neon (sadly, the Armada 385 is
castrated upstream since the 370 only supports VFPv3-D16 :/).

diff --git a/target/linux/mvebu/cortexa9/target.mk
b/target/linux/mvebu/cortexa9/target.mk
index cdd4d86e49..9af3c95d7b 100644
--- a/target/linux/mvebu/cortexa9/target.mk
+++ b/target/linux/mvebu/cortexa9/target.mk
@@ -10,5 +10,5 @@ include $(TOPDIR)/rules.mk
 ARCH:=arm
 BOARDNAME:=Marvell Armada 37x/38x/XP
 CPU_TYPE:=cortex-a9
-CPU_SUBTYPE:=vfpv3-d16
+CPU_SUBTYPE:=neon
 KERNELNAME:=zImage dtbs

Then, I use the attached configuration files. The .config (for
OpenWrt) in the buildroot, and config-default (for the kernel itself)
in target/linux/mvebu/cortexa9/.

Let me know if you need anything else!

Thanks,
Rui
