The macro GOOGLE_PROTOBUF_ARCH_PPC is not used anywhere in the protobuf
source; there is no Power-specific atomics implementation, etc.
Funnily enough, the macro __ppc__ is not actually defined on 32-bit

Before, every charAt would emit (on android):
```
0x00002104 adrp x17, #+0x1000 (addr 0x3000)
0x00002108 ldr w17, [x17, #20]
0x0000210c ldr x0, [x0, #128]
0x00002110 ldr x0, [x0, #328]
0x00002114 ldr lr, [x0, #24]
0x00002118 blr lr <-- Call into String.charAt(int)
```
Now, it emits the inlined implementation of charAt (branch is for possibly compressed strings):
```
0x000020b4 ldur w16, [x4, #-8]
0x000020b8 tbnz w16, #0, #+0xc (addr 0x20c4)
0x000020bc ldrb w4, [x4, x0]
0x000020c0 b #+0x8 (addr 0x20c8)
0x000020c4 ldrh w4, [x4, x0, lsl #1]
```
