this was changing:
	elf_flags 0x<something> -> 0
	fpu_type 0 -> 2
but should have changed:
	elf_flags 0x<something> -> 0x<something>
	fpu_type 0 -> 2

this was changing:
	elf_flags 0 -> 0x<something>

but should have changed:
	elf_flags 0x<something> -> 0x<something>
	fpu_type 2 -> 2
i.e., no change
