f8d2c65fd9 sandbox: fix compiling of cpu/os.c
U-boot itself generally builds with -nostdinc.  This is because the
bootloader needs to be completely standalone.  In the sandbox arch
though, we need a little bit of code to glue the u-boot world to the
host operating system, and we need to be able to access the host
libc's headers in order to do so.

Currently, we're using -I/usr/include to workaround the global
-nostdinc, but that doesn't work for everyone and for all headers.
Instead, let's filter out -nostdinc when building the os.c code.

Without this patch, some distros hit errors such as:
---8<---
In file included from /usr/include/fcntl.h:27:0,
                 from os.c:22:
/usr/include/features.h:323:26: fatal error:
     bits/predefs.h: No such file or directory

Using mmap to allocate memory from the OS for RAM simulation we can use
u-boot own malloc implementation.

This allows us to act like a serial device: we get tab chars and CTRL+C

9660e442de cosmetic: s/BOARD_LATE_INIT/CONFIG_BOARD_LATE_INIT
This renames BOARD_LATE_INIT to CONFIG_BOARD_LATE_INIT.
Along the way it removes some leftover

 #define BOARD_LATE_INIT		1

and adds some basic documentation for board specific
callbacks in README.

We want to keep all OS-dependent code in once place, with a simple interface
to U-Boot. For now, this is that place.

b8605a1cbd sandbox: Add architecture lib files
These files are taken from the ARM board implementation and then reduced
to remove unneeded cruft.

Ideally we would work towards unifying arch/xxx/lib files, particularly
board.c.

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.
