[Dev] Minor mips64el cleanup on repo

[Luke Shumaker]

I just did some cleanup on repo.parabola.nu. I...
 - remove '/mips64el/packages/abslibre/' per
   https://labs.parabola.nu/issues/591
 - moved '/toolchains/' to '/mips64el/toolchains/'
 - removed all empty directories in '/mips64el/'
 - excluded '/mips64el/' from being mirrored
 - removed '/{~smv,~jorginho,~emulatorman,cross,kernels}/os/mips64el/' they
   only had .{abs,db,files}{,.tar.gz} (if at all).
   - Each of the .abs.tar.gz files only had the file 'tmp/hello'
     (which is empty).
   - Some of the other repos have entries for packages in them:
     - ~smv:gitosis-git-20110625-1 (does not exist)
     - ~jorginho:urbanterror-data-4.1.1-2 (does not exist)
     - ~emulatorman:ath9k-htc-firmware-git-20140911-1 (exists as a torrent)
     - ~coadde:glproto-git-20120612 (does not exist)
     - ~coadde.old:foobar-1-1.nonprism1 (exists as a torrent)
     - kernels:pax-flags-libre-2.0.17-1 (exists as a torrent)
