libc/eglibc: Add option that allows for getting svn over http://

Instead of getting eglibc over standard svn://svn.eglibc.org
Add an option that allows the user to get source from
http://www.eglibc.org/svn

This is useful if you are behind a firewall or proxy.
If you are behind a proxy, don't forget to configure
${HOME}/.subversion/servers

In the [global] section setup your proxy configuration.
