Subject: [[PATCH v2 core-updates] 12/37] libgcrypt: Fix cross-compilation
 build error.
Date: Fri, 18 Jun 2021 18:09:11 +0200

When cross-compiling a package using gnu-build-system,
%build-inputs does not exist. But libgcrypt uses %build-inputs
anyway. Fix it.

* gnu/packages/gnupg.scm
  (libgcrypt)[arguments]<#:configure-flags>: Make this a G-exp
  instead of a raw S-exp. Eliminate %build-inputs and use
  this-package-input instead.
