I think TCL_LIBRARY and TK_LIBRARY are supposed to be set the the name
of the library files, not to the directory which contains them.

You can just define TCL_STUB_LIBRARY with -D as well, assuming it's
not automatically found after you fix TCL_LIBRARY and TK_LIBRARY -D
values...

  -DTCL_STUB_LIBRARY=/free/cross-compilation-binaries/win32-ix86/tcl/lib/libtclstub86.a
