As discussed on IRC, keeping bootstrap Guile on 2.0 simplifies adding new
architectures and removes the need for parameterizing
gnu/packages/bootstrap.scm.
This reverts commit 2acfe022a7.
* gnu/packages/make-bootstrap.scm (%guile-static): Revert to guile-2.0. Retain
build recipe.
* gnu/packages/patches/guile-relocatable.patch: Update for Guile 2.0.14.
