downloadguix-5c93d2332493a8e7edb07e8863b58c0ca1696280.tar.gz
gnu: guile-bootstrap: Use a fixed-output derivation to download.
* gnu/packages/bootstrap.scm (bootstrap-guile-url-path)
(bootstrap-guile-hash, download-bootstrap-guile): New procedures.
(raw-build): Use it.  Script uses $GUILE_TARBALL.  Add GUILE to the
inputs of the derivation.
