Change the way we decide whether to build gtcltk-lib, so that it's

omitted from the build process when appropriate, but never from
the dist process.
* configure.in: Don't edit all_subdirs depending on the
availability of Tk; let that be the list of all PLUGIN
subdirectories present, as it used to be.  Instead, edit a new
variable, build_subdirs; write its final value, the list of
subdirs we do want to compile in, to config.build-subdirs.
Substitute that into the top-level Makefile too.
* Makefile.in (subdirs): Set this to @build_subdirs@, so we only
recurse on the subdirectories we should build.
(distdirs): Set this to @existingdirs@, so it includes the subdirs
we decided not to build.

* configure.in: If we can find the library for tcl7.5, build
gtcltk-lib.  Call AC_PROG_CC, to help run that test with the right
compiler (not sure this is necessary).

### build_subdirs is the list of directories we actually want to
### build. It's not equivalent to existingdirs: if we can't find the
### Tcl libraries, then we don't want to build in gtcltk-lib.
###
### So why can't we just forget about gtcltk-lib altogether, and
### delete it from existingdirs, in that case? Well, in order for
### 'make dist' to work, we still need to configure gtcltk-lib, and
### the top-level Makefile needs to know it exists,
build_subdirs="${existingdirs}"
### Decide which directories to build; remove the ones we don't want
### from build_subdirs.
### Use gtcltk-lib only if we seem to have Tcl installed on the
### system. We really should check for Tk as well, but that involves
### finding all the X libraries that we need to do a complete link.
