Since we link purgatory with -r aka we enable "incremental linking" no checks for unresolved symbols are done while linking the purgatory. This commit adds an extra check for unresolved symbols by calling ld without -r before running objcopy to generate purgatory.ro. This will help us catch missing symbols in the purgatory sooner. Note this commit also removes --no-undefined from LDFLAGS_purgatory as that has no effect.

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.
