- 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.
