Tom Rini 699946ae61 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.
