ld.lld 16.0.0 and newer defaults to '--no-undefined-version', which causes the following error when CONFIG_MIPS_CLOCK_VSYSCALL is not set: ld.lld: error: version script assignment of 'LINUX_2.6' to symbol '__vdso_gettimeofday' failed: symbol not defined Only export __vdso_gettimeofday() when it will be present in the final object file, which clears up the error.
