Switched to other bits of work temporarily:

With instructions at http://rhombus-tech.net/allwinner/a20/boot/ for
compiling u-boot-sunxi

    git clone https://github.com/linux-sunxi/u-boot-sunxi.git
    cd u-boot-sunxi
    make CROSS_COMPILE=arm-linux-gnueabihf- EOMA68_A20_FEL

That worked with /usr/bin/arm-linux-gnueabihf-gcc sym linked to
arm-linux-gnueabihf-gcc-4.4  (Ubuntu 12.04.3)

[Spotted a potential bug in u-boot-sunxi/common/cmd_gpio.c line 30 need
to change ulong value; to ulong value=69; or something similar to
prevent uninitialised return value]



Going back to original problem...
Searching for linux-sunxi found it 
 -    git clone https://github.com/linux-sunxi/linux-sunxi.git


Then tried this again:
make -j3 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
KDIR=~/code/linux-sunxi/ -C arch/arm/mach-sun7i/pm/standby all



I got this:

Not sure what cc1: error means.
