Update ChaCha20 ARM asm with sections.
The ChaCha20 ARM asm is generated from GCC. This change updates the GCC
command line to include -ffunction-sections, which causes GCC to put
each function in its own section so that the linker with --gc-sections
can trim unused functions.
Since the file only has a single function, this is a bit useless, but
it'll now be consistent with the other ARM asm.
