distro: Add patch to allow the bootstrap Guile to work without iconv.

* distro/patches/guile-default-utf8.patch: New file.
* Makefile.am (dist_patch_DATA): Add it.

* distro/packages/base.scm (%guile-static): Use it.
  (%guile-static-stripped): Add call to `remove-store-references'.

+This hack makes Guile default to UTF-8.  This avoids calls to
+`iconv_open'; `iconv_open' tries to open shared objects that aren't
+available during bootstrap, so using UTF-8 avoids that (and UTF-8 has
+built-in conversions in glibc, too.)
