When building an SPL image, override the link flags so that it uses the
system libraries. This is similar to the way the non-SPL image is built.

- The macro __BIGGEST_ALIGNMENT__ is gcc-specific. If it is not defined
we'll just assume 16. This is correct for at least the common cases
and LLVM does not provide an equivalent macro.
- When linking U-Boot we're passing -T to the linker, and while gcc will
just pass this along with LLVM we need to be specific.

We have done with the generic board conversion for all the boards
of ARC, Blackfin, M68000, MicroBlaze, MIPS, NIOS2, Sandbox, X86.
Let's select SYS_GENERIC_BOARD for those architectures, so we can
tell which architecture has finished the conversion at a glance.

An option is provided to avoid using SDL in U-Boot sandbox (and drop
support for the LCD). However the check in the Makefile is too late
and warnings are printed even if NO_SDL=y is given.
Adjust the order to avoid this warning.

Some machines do not have SDL libraries installed, and it is still useful
to build sandbox without LCD/keyboard support.
Add an option for this, used as follows:
make sandbox_config all NO_SDL=1

SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which
provides simple graphics and sound features. It works under X11 and also
with a simple frame buffer interface. It is ideally suited to sandbox
U-Boot since it fits nicely with the low-level feature set required by
U-Boot. For example, U-Boot has its own font drawing routines, its own
keyboard processing and just needs raw sound output.
We can use SDL to provide emulation of these basic functions for sandbox.
This significantly expands the testing that is possible with sandbox.
Add a basic SDL library which we will use in future commits.

Add support for building a device tree for sandbox's CONFIG_OF_HOSTFILE
option to make it easier to use device tree with sandbox.
This adjusts the Makefile to build a u-boot.dtb file which can be passed
to sandbox U-Boot with:
./u-boot -d u-boot.dtb

Sandbox doesn't actually provide U-Boot access to the machine's physical
memory. Instead it provides a RAM buffer of configurable size, and all
memory accesses are within that buffer. Sandbox memory starts at 0 and
is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer
might produce unpredictable results in the event of an error, and would
expose the host machine's memory architecture to the sandbox U-Boot.
Most U-Boot functions assume that they can just access memory at given
address. For sandbox this is not true.
Add a map_sysmem() call which converts a U-Boot address to a system
address. In most cases this is a NOP, but for sandbox it returns a
pointer to that memory inside the RAM buffer.
To get a U-Boot feature to work correctly within sandbox, you should call
map_sysmem() to get a pointer to the address, and then use that address for
any U-Boot memory accesses.

Since we provide all our own library calls, the fortification from
glibc just gets in our way (which some distros enable by default).

This is an initial implementation with all functions defined but not working.
The lds file is very simple since we can mostly rely on the linker defaults.
