On x86_64 we need CONFIG_PHYS_ADDR_T_64BIT to make the resource sizes
64bit. The kernel has this as a Kconfig variable, but on barebox sandbox
will build with whatever compiler we find, so we can't put it into Kconfig.

To be able to use the sandbox with fat filesystem support unaligned.h is needed.
It tries to be general in selecting little endian or big endian on a gcc macro.

We never had interrupt support in barebox and we have no plans to
add interrupt support. Even if we do I doubt the current fragments
of irq support are helpful, so remove them.

When building sandbox with ccache, one would hit warnings such as:
warning: 'struct mmsghdr' declared inside parameter list
on random files; a way to reproduce this issue is to build a simple
file doing just:
#include <sys/socket.h>
int main(void) {
return 0;
}
gcc -Wall -P -c -o foo foo.c
But actually the -P flag is only useful when generating non-C files,
such as linker scripts in the case of barebox. Removing the -P flag
from all the gcc invocations, except when generating .lds files makes
the warning go away. It turns out that this is what
linux/scripts/Makefile.build also does nowadays.

Until now, the main function of the sandbox port wants to use the libc
getopt(), but as we have a getopt() implementation in barebox as well,
it is silently used instead. This works in the usual case, but if an
error occurs (i.e. by using an unknown argument) in getopt(), the
implementation tries to write to the console, which is not initialized
and thus breaks with a null pointer exception.
This patch changes the main function to use getopt_long() instead of
getopt(). This makes us use the implementation in glibc and while being
there, we get long options, which makes us look more professional...
