[PATCH 1/1] sandbox: move ELFCLASS detection to asm/elf.h

[PATCH 1/1] sandbox: move ELFCLASS detection to asm/elf.h

[Jean-Christophe PLAGNIOL-VILLARD]

now we can detect the host build from gcc macro
and cross compile the sandbox

for 64bit today we just detect x86_64 and powerpc64
by default barebox will use 32bit elf class

	to build on most of arch you need this fix and 3 others
	already in the next

	commit	9a5898e5: sandbox: simplify linker script
	commit	15f87657: sandbox: remove duplicate barebox.lds.S
	ommit	e3e71f5e: sandbox: move __SANDBOX__ to Makefile

	Sacha those 4 patches could go to the master as they fix the sandbox

Best Regards,
J.
