USE_LLVM_SHLIB := 0 not statically linking llvm on Linux, julia 1.2.0-rc2

[Orbots]

CentOS 6 with gcc 6.4.0 building from:
https://github.com/JuliaLang/julia/archive/v1.2.0-rc2.zip

I had to employ this patch to get LLVM statically linked into libjulia.so and avoid a dependency on libLLVM-6.0.so

Thank you for the diff and report, we discourage statically building LLVM, since it will block parts of the ecosystem using LLVM.jl like CUDAnative.jl

Ah ok. It's a fix I found for some LLVM symbol mixing issues I've encountered. #32616
Cheers.
