Commit63ffe00d8c("kbuild: Fix running modpost with musl libc") accidentally turned the unresolved symbol warnings into errors when vmlinux.o (for in-tree builds) or Module.symver (for external module builds) is missing. In those cases, unresolved symbols are expected, but the -w option is not set because 'missing-input' is referenced before set. Move $(missing-input) back to the original place. This should be fine for musl libc because vmlinux.o and -w are not added at the same time. With this change, -w may be passed twice, but it is not a big deal.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
