Compile loader only once
Callers must pass ELF machine, byte swapping and symbol LSB clearing
information to ELF loader. A.out loader needs page size information, pass
that too as a parameter.
Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw.
Adjust callers. Also use target_phys_addr_t instead of target_ulong for
addresses: loader addresses aren't virtual.
