If your build was configured with `DEFAULT_SYSROOT` to a toolchain path that has a `/include` directory, then the contents of that directory would be picked up. The intent of the person doing the build with regards to `DEFAULT_SYSROOT` is to provide a sysroot for their intended targets, which may not match the needs of the explicit target provided here.
