We need a mechanism for BarOS to decide which Foo revision they want. Now suppose, there's another distribution called FredsOS. It too has the triple foo-linux-gnu but wants to target Foo revision 3. If clang changed to accommodate BarOS, then FredsOS is in the same position as BarOS version 2 was. The same thing happens with cross-compilers. Using the mips-mti-linux-gnu toolchain as an example: Mentor release a mips-mti-...
