CPU Cache Utils to remove in Android build config! (unnecessary)

[Daniel Weck]

Well, unless ENABLE_SYS_CACHE_FLUSH is defined, the "CPU cache util" stuff should not be included in the build:
https://github.com/readium/readium-sdk/blob/develop/ePub3/utilities/byte_buffer.cpp#L27

#ifdef ENABLE_SYS_CACHE_FLUSH
#include "CPUCacheUtils.h"
#endif //ENABLE_SYS_CACHE_FLUSH
...
...

void ByteBuffer::Clean(unsigned char *ptr, size_t len)
{
    bzero(ptr, len);

#ifdef ENABLE_SYS_CACHE_FLUSH
    epub_sys_cache_flush(ptr, len);
#endif //ENABLE_SYS_CACHE_FLUSH
}

Ah, I see that the "CPU Cache Utils" are included in the build (they can be removed, as they are unused):

https://github.com/readium/readium-sdk/blob/develop/Platform/Android/epub3/Stable.mk#L242
https://github.com/readium/readium-sdk/blob/develop/Platform/Android/epub3/Experimental.mk#L241
