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

v3:
fix typo
v2:
as discuss with Loïc use the size of the pointer
Loïc
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.
