This adds simple command-line parsing to sandbox. The idea is that it
sets up the state with options provided, and this state can then be
queried later, as needed.
New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro,
pointers are automatically gathered up in a special section, and
then the core code takes care of gathering them up and processing
at runtime. This way there is no central place where we have to
store a list of flags with ifdefs.

In order to pass command line arguments to sandbox we need to be able
to act on them. So take control back at the end of board_init_r() from
where we can call the main loop or do something else.

The state exists through the life of U-Boot. It can be adjusted by command
line options and perhaps later through a config file. It is available to
U-Boot through state_...() calls (within sandbox code).
The primary purpose of this is to contain the "hardware" state. It should
only be used by sandbox internal code.

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<---

/usr/include/features.h:323:26: fatal error:

Along the way it removes some leftover
