Original change's description:
> Use -malign-double for x86 android
> 
> For double, long double and long long variables, they align to one
> word boundary on x86, and 2 word boundary on x64 by default. This
> is a big problem for android webview, as its render and browser
> processes run x86 and x64 repectively. The data structs in shm may
> have such misalignment problems.
