Snapshot rustc depends on libtinfo.so.5

[sfackler]

libtinfo is part of ncurses, but is not always compiled into a separate library. On Arch Linux, for example, trying to compile raises this error:

x86_64-unknown-linux-gnu/stage0/bin/rustc: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory
make: *** [x86_64-unknown-linux-gnu/stage0/lib/rustc/x86_64-unknown-linux-gnu/lib/libstd.so] Error 127

Running

sudo ln -s /usr/lib/ncurses.so.5 /usr/lib/libtinfo.so.5

fixes the problem, but isn't a great solution.

Odd... why does rust link against ncurses at all?

[sfackler]

Grepping through the source, it looks like the only references to tinfo are in llvm, so it may be coming from there.

Hmm, we may need to configure LLVM differently. We need to figure out how to build only what we want from LLVM, not all of the other nonsense that we're pulling in (JIT tests, random tools, etc.)

We need to fix this regression for the 0.8 release, so I'm setting it as the milestone.
