[SV 40254] Modify build.sh to work properly with Guile support.

* guile.c (guile_gmake_setup) [HAVE_GUILE]: Define a stub function
when Guile support is not enabled.
* main.c (main) [HAVE_GUILE]: Always invoke guile_gmake_setup().
* Makefile.am: Make guile.c standard, not optional.
* build.template: Add the Guile compiler and linker flags.
