Same compiler? Clang bloats the boot code rather substantially, even after
all the flags to tell it to generate smaller code are used. gcc 4.2.x
built stuff
was substantially smaller.

There's a 520kb limit enforced in the boot1 for similar reasons. Looks like
the combination of options makes us use just enough extra memory to
sink the battleship...
