I see the same issue on my Skylake desktop (sig=0x506e3). The microcode updates at startup (microcode: microcode updated early to revision 0xc2, date = 2017-11-16) but I still get "Intel Spectre v2 broken microcode detected; disabling Speculation Control". I also tested it on Ivy Bridge, Broadwell, and another Skylake system (0x406e3) and it works properly on all those.
