ARM crash due to non-aligned memory access

On some ARM systems accessing 32-bit values at non-4-aligned addresses crashes
or silently reads incorrect data (depending on how kernel handles non-aligned
access trap). This patch ensures that if any of the strings are not 4-byte
aligned, we do the slower, but working, 16-bit access.
