llvm linking build break

[mskrzypkows]

I have a build break on my Ubuntu 14.04

configure: WARNING: Building mesa with statically linked LLVM may cause compilation issues
/usr/lib/llvm-3.4/lib/libLLVMSupport.a(Process.o): In function `llvm::sys::Process::FileDescriptorHasColors(int)':

collect2: error: ld returned 1 exit status

Is it connected with this issue: rust-lang/rust#36854 ? How to make it build?

These missing symbols come from libncurses, it seems? For some reason
LLVM uses them. Can you check if installing any of the libncurses
packages for Ubuntu fixes it?

Or perhaps libedit-dev?

[mskrzypkows]

I have libncurses5, libncurses5-dev and libedit-dev installed, it doesn't help.

I get the same error on Travis-CI: https://travis-ci.org/servo/servo-with-rust-nightly/builds/274556830#L3219

Adding language: python to the Travis config "fixed" it, so it was probably some missing dependency.

#23 should fix this, let's see what the buildots say.
