MIPS: VDSO: Conditionally export __vdso_gettimeofday()
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.
