Since MIPS has removed this, we should remove it too. In fact, other architectures also use $(LD).

       fe00e50b2db8 ("ARM: 8858/1: vdso: use $(LD) instead of $(CC) to link VDSO")
       691efbedc60d ("arm64: vdso: use $(LD) instead of $(CC) to link VDSO")
       2ff906994b6c ("MIPS: VDSO: Use $(LD) instead of $(CC) to link VDSO")
       2b2a25845d53 ("s390/vdso: Use $(LD) instead of $(CC) to link vDSO")

If Huacai is willing to apply this patch, I suggest supplementing the commit message.
