tcl8.6.12

[Bruce Dubbs]

New point version.

Website has changed to ​https://www.tcl.tk/software/tcltk/download.html so currency needs to be updated also.

[Bruce Dubbs]

Fixed currency at commit 1f8c0b947ef4cbba2afcf77f903a808faae9a992

[Xi Ruoyao]

Take new LFS packages, will use them in my Chapter 8.

I'll keep the note about unixInit-1.2 failure there, though I didn't see the failure.

If everyone doesn't see the failure we can remove the note later.

[Bruce Dubbs]

For me, I got

all.tcl: Total 137 Passed 121 Skipped 16 Failed 0

but that was in a full system. We need to check the results in chroot and with a partial build. tcl is only 13 packages into Chapter 8.
