web/download: Update Linux Static Build links

* Remove Burek's builds
These have been halted since 16 July. Burek has been notified several
times, but I have recieved no response. Link will be re-added if
activity resumes.

* Add reference to 32-bit builds to relaxed's link
Thanks to relaxed for quickly volunteering to provide 32-bit builds,
and thanks to Burek for all of his previous work.
