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.

The only safe solution is "make clean && make". Any other solution
risks of giving you an inconsistent filesystem in terms of library
dependencies.
