7a26aee61bbbd8e37745ce13433545333eac4505 whereby (gnu packages
pkg-config) would be caught in a cycle, leading to miscompilation of
package modules, in turn leading to failure to compute the Guix
derivation with exceptions like:

  1. &amp;package-input-error:
      package: #&lt;package libgc@8.2.4 7fee96c4dc60&gt;
      input: ("_" #&lt;syntax-transformer pkg-config&gt;)

* gnu/packages/pkg-config.scm: Autoload (gnu packages check).
