sandbox: Fix building with LLVM
- The macro __BIGGEST_ALIGNMENT__ is gcc-specific. If it is not defined
we'll just assume 16. This is correct for at least the common cases
and LLVM does not provide an equivalent macro.
- When linking U-Boot we're passing -T to the linker, and while gcc will
just pass this along with LLVM we need to be specific.
