sandbox: allow cross-compiling sandbox
UEFI test files like helloworld.efi require an architecture specific
PE-COFF header.
Currently this does not work for cross compiling. If $CROSS_COMPILE is set,
use the first part of the architecture triplet from the variable to
choose the PE-COFF header.
Now we can cross-compile the sandbox, e.g.
make sandbox_defconfig NO_SDL=1
CROSS_COMPILE=/opt/bin/aarch64-linux-gnu- NO_SDL=1 MK_ARCH=aarch64 make
