    (description
     "The primary goal of this project is to define a portable and efficient C
programming interface (API) to determine the call-chain of a program.  The API
additionally provides the means to manipulate the preserved (callee-saved)
state of each call-frame and to resume execution at any point in the
call-chain (non-local goto).  The API supports both local (same-process) and
remote (across-process) operation.  As such, the API is useful in a number of
applications.")

specifying a #:user not available in the build environment would fail
validation.

bindings.  In future versions, autoloading a module gives access only to
the listed bindings, as per #:select (see &lt;https://bugs.gnu.org/38895&gt;).

This commit adjusts autoloads to the new semantics, allowing Guix to be
built with Guile 2.9.7/2.9.8.
