Remove LIBGCRYPT and LIBGCRYPT_LIBDIR assignments. * m4/guix.m4 (GUIX_ASSERT_LIBGCRYPT_USABLE): Remove. * README: Add Guile-Gcrypt to the dependencies; move libgcrypt as "required unless --disable-daemon". * doc/guix.texi (Requirements): Likewise. * gnu/packages/bash.scm, guix/derivations.scm, guix/docker.scm, guix/git.scm, guix/http-client.scm, guix/import/cpan.scm, guix/import/cran.scm, guix/import/crate.scm, guix/import/elpa.scm, guix/import/gnu.scm, guix/import/hackage.scm, guix/import/texlive.scm, guix/import/utils.scm, guix/nar.scm, guix/pki.scm, guix/scripts/archive.scm, guix/scripts/authenticate.scm, guix/scripts/download.scm, guix/scripts/hash.scm, guix/scripts/pack.scm, guix/scripts/publish.scm, guix/scripts/refresh.scm, guix/scripts/substitute.scm, guix/store.scm, guix/store/deduplication.scm, guix/tests.scm, tests/base32.scm, tests/builders.scm, tests/challenge.scm, tests/cpan.scm, tests/crate.scm, tests/derivations.scm, tests/gem.scm, tests/nar.scm, tests/opam.scm, tests/pki.scm, tests/publish.scm, tests/pypi.scm, tests/store-deduplication.scm, tests/store.scm, tests/substitute.scm: Adjust imports. * gnu/system/vm.scm: Likewise.
