The Kconfig symbols required for the Allwinner F1C100 (MACH_SUNIV) are
currently not selected by any defconfig. sunxi_defconfig only covers the
v7 SoCs, but the F1C100s is ARMv5, so we cannot share a single image.
Add the required symbols to multi_v5_defconfig, to give people some sane
default config when playing around with this chip. This is probably more
important as there are surely not many distros out there supporting
ARMv5 out of the box.
This allows my LicheePi Nano board to boot to a busybox prompt.
The zImage size grows by about 50 KB, in detail:

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
