Yes,I am doing a cross compile.
There is no way to compile natively.

The max_ranges directive is to limit the number of ranges in a
request, which almost always at most one (and just one in the
request you've showed).  And it is completely unrelated to 416
errors.  Just leave the default.

What does "./configure" output show?  Are you running configure on
the target system, or tried to cross-compile nginx?

It looks like for some reason nginx wasn't able to find out how to
instruct your system to use 64-bit off_t.  The most likely reason
I can think of is an attempt to cross-compile nginx.  Note that
cross-compiling is not supported and not going to work.  The most
simple and the only supported solution would be to compile nginx
natively.
