Prevent unloading shared libraries on Linux when dlclose() is called. This is necessary since command-line option parsing API relies on registering the global option instances in the option parser instance which can be loaded in a different shared library. Given that we can't reliably remove those options when a library is unloaded, the parser ends up containing dangling references. Since glibc has relatively complex library unloading rules, some of the LLVM libraries can be unloaded while others (including the Support library) stay loaded causing quite a mayhem. To reliably prevent that, just forbid unloading all libraries -- it's a very bad idea anyway. While the issue arguably happens only with BUILD_SHARED_LIBS, it may affect any library reusing llvm::cl interface. Based on patch provided Ross Hayward on https://bugs.gentoo.org/617154.

Low Level Virtual Machine (LLVM) ================================ This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments. LLVM is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt. Please see the documentation provided in docs/ for further assistance with LLVM, and in particular docs/GettingStarted.rst for getting started with LLVM and docs/README.txt for an overview of LLVM's documentation setup. If you are writing a package for LLVM, see docs/Packaging.rst for our suggestions.
