Man entry for sendfile:
Not specified in POSIX.1-2001, or other standards.
Other UNIX systems implement sendfile() with different semantics and
prototypes. It should not be used in portable programs.
Select PLATFORM_LINUX if enabling FEATURE_USE_SENDFILE.

When enabled, busybox will use the kernel sendfile() function
instead of read/write loops to copy data between file descriptors
