Subject: [PATCH] build: remove contents of build/runtime/doc/* surgically
 (#8024)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Only remove the directory contents. If the directory itself is removed,
then `sudo make install` creates a root-owned …/doc/ directory. That
breaks the next non-root build.

This was an accident of 0b1904d835a2.

Note: the following does not work, because it misses renamed help files
(which would no longer be in the build-tree definition)

    COMMAND ${CMAKE_COMMAND} -E remove ${BUILDDOCFILES} ${GENERATED_HELP_TAGS}
