* gnu/packages/icu4c.scm (icu4c): Download via sourceforge mirrors.  The
  previous URL,
  http://download.icu-project.org/files/icu4c/55.1/icu4c-55_1-src.tgz,
  redirects to sourceforge, which then fails because that redirects to
  https and as the original URL didn't start with HTTPS, gnutls wasn't
  included in the downloader.

  to fetch tarballs via https.  freedesktop.org appears to have updated
  recently to redirect all http to https.  As an exception, we leave
  pkg-config like it is, because pkg-config is needed to build gnutls,
  and without gnutls we can't download https URLs.
