[cfe-dev] Supporting multiple targets from a single 'clang' installation

[David Chisnall via cfe-dev]

You can use --sysroot= to specify the path for headers and libraries and -B to specify the path for tools (e.g. linker and assembler).  There is currently no way of having a single clang symlink the has a custom -target, --sysroot, and -B, though there was some discussion recently of providing config files that do this.

I have no problem getting this to build and generate code, but where I am running into trouble is in the configuration of where the headers and libraries should reside.
