distcheck fixen

* examples/Makefile.am: Fix the installed guile-config invocation to set
  PKG_CONFIG_PATH.

* meta/Makefile.am (EXTRA_DIST): Dist the bin_SCRIPTS.

* meta/guile-config (pkg-config): Better error messages if pkg-config
  invocation fails.

* meta/uninstalled-env.in (PATH): Now that guile-config and guile-tools
  are not generated, make it the srcdir/meta instead of the builddir.
  (Guile itself will be picked up from libguile.)
