cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
(libpath.h, versiondat.h): Replaced dependency on Makefile with
dependencies on $(srcdir)/Makefile.in
$(top_builddir)/config.status in order to avoid circularity.
* configure.in (GUILE_LIBS): New variable. Contains libraries
which libguile needs to be linked with. Substituted into
libpath.h.
* threads.m4 (threads_package): Don't add $LDFLAGS and $LIBS to
$cy_cv_threads_libs.
