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
I suggest ddoing it the other way, enable sendfile only for Linux.
As it is, sendfile is enabled by default, which would automatically
select Linux, which might select other things that don't work on
non-Linux systems.
