Old thread, but I have an observation to add: when configure is being run with the --disable-tcl argument, the Makefile variables needed to build anything tcl-ish (including sqlite3_analyzer) are not set properly (TCC, LIBTCL). "make sqlite3_analyzer" will therefore fail.
So I think tcl headers and libraries should be looked for even in the presence of --disable-tcl. See the attached patch for how it might work. I hereby declare this patch to be public domain, no strings attached, which I'd gladly repeat in form of an [affidavit](https://sqlite.org/copyright.html) if you tell me how to do this.
BTW, after running automake, I get errors about the recently added AMALGAMATION_LINE_MACROS.
