Ralph Giles 897e3e8e03 Bug 1063356 - Define __ANDROID__ for libvpx asm. r=kinetik,mshal
The assembly relies on __ANDROID__ to decide whether to call
'lrand48' or 'rand'. The later is available on desktop but
only on Android L or later. However, this macro isn't defined
by the linux vpx_config asm file we use for x86 Android builds,
so we must pass it manually when invoking yasm.
