configure: do not require svn

svn is needed to download eglibc from the upstream repository.
In some situations, though, it can happen that:
 - the developpers' machines do not have svn
 - a LAN mirror has been set-up with pre-downloaded eglibc tarballs
In this case, it makes sense not to hard-depend on svn.

So, if svn is missing, just say so, and add a comment in the
menuconfig.
