Patch for supporting 'use_system_lib' on Linux

[Michael van der Westhuizen]

Hi All,

As per Daniel's commit message in libcxx r174404, here's Linux support for the use_system_lib parameter.

To use the freshly built libcxx without installing it in CMake you'll need to pass '-DLLVM_LIT_ARGS=-sv --param use_system_lib=0' to your CMake call (as this defaults to True to match the Darwin behaviour).

This is a deviation from previous behaviour (which was to unconditionally use the freshly built libcxx), so perhaps the logic under Linux needs to be reversed?

Michael
