[Help-smalltalk] [PATCH] build-aux/tcltk.m4: Simplify tclConfig.sh searching

[Lee Duhem]

Hi,

Even if my building system already has tclConfig.sh, configure script
still cannot find it,
because it is looking at the wrong places.

According to Tcl wiki article [1], the following Tcl code can give the
location of tclConfig.sh
directly:

[::tcl::pkgconfig get libdir,install]

So we can use it to simplify the searching rules in build-aux/tcltk.m4.

Tested on Fedora 25 and Ubuntu 14.04, looks like working on both systems.

Regards,
libin
