Reverting the patch that disabled using the 'binutils snapshot', because it's

needed for the fuloong minipc. It was not enough having the loongson2f patches;
only having the patches, we got troubles building cups with a segfault on the
dynamic loader running their 'genstrings' program.  And if sysvinit needs newer
binutils (I can't remember why, but I wrote it in the all-packages.nix before),
then let's use the snapshot.

As a note about "why this snapshot" (civodul was interested), when I knew that
we needed an unreleased version of binutils I went to download the snapshot of
the day. And it worked. This is all the story.
