[OBV][PATCH] Fix Arm build

[Alan Hayward]

[Should have checked this when I fixed s390 build.
 Going to see about getting an Arm box into buildbot - booting Linux
 in Qemu-AArch64 in AArch32 mode on a AArch64 box might be fast enough to
 use as an Arm machine]


Add missing include.

        * arm-linux-nat.c: Add include.
