substitute: Honor client-provided empty URL list.
Before that, 'guix build --substitute-urls=""' would lead to using the daemon's own URL list instead of the empty list. The 'or*' hack, which is to blame, had become unnecessary since commit fb4bf72be3fbc23bca35ba4b842b7e1517ef0e3a. Reported by Mark H Weaver <mhw@netris.org>. * guix/scripts/substitute.scm (or*): Remove. (%cache-urls): Use 'or' instead of 'or*'. * tests/store.scm ("substitute query, alternating URLs"): Add test with empty URL list. * doc/guix.texi (Common Build Options): Mention the empty string.
