Need to fix .s writing

[rjkiv]

Now that we're working to get scratch functionality, being able to write .s's is important. Currently, .s writes fail on non-4-byte aligned data (which is possible in X360). And on top of this, we need to able to automatically generate a macros.inc, as well as remove the ELF-isms in the current .s routine (namely removing @ha and @l from relocs).

# 0x82F5E180..0x82F5E184 | size: 0x4
.section .bss, "wa", @nobits
.balign 8

should become

# 0x82F5E180..0x82F5E184 | size: 0x4
.section .bss
.align 3 (because 2^3 = 8)

etc

Update: Non-4-byte aligned data has seemingly been solved thanks to free's latest PR. Now, we just need to un-elf the currently generated .s files, because the Xbox 360 uses BE PPC COFFs.

We'll know that this issue is solved if jeff-created .s files can be assembled using encounter's patched Xbox 360-friendly binutils assembler into COFFs without any issues.
