If you're using the Sourcery CodeBench toolchain (formerly known as CodeSourcery toolchains), then you are using an external toolchain, and the toolchain never gets rebuilt. > Anyway, for my real question, is there a solution?

Any other solution risks of giving you an inconsistent filesystem in terms of library dependencies.
