[TCLCORE] Tcl/Tk 8.6b1 Release Candidate

[<dg...@ni...>]

A number of problems with the build scripts
on various platforms have been corrected.
The RC1 tarballs are now at

ftp://ftp.tcl.tk/pub/tcl/tcl8_6/

The changes file updates are also complete,
so unless there are more really big troubles
uncovered, I'll promote these to become
8.6b1, probably on Tuesday.
