Subject: [PATCH] linux-doc: Fix up symlinks to gzipped docs

Some files are moving around under Documentation and being replaced
with symlinks.

gzip -r doesn't even check for symlinks, and fails when they're broken
(which happens if the destination was found first).  So use find and
xargs instead, and deal with the symlinks separately.
