* gnu/packages/make-bootstrap.scm (hurd-triplet?): Move it from here.. * gnu/packages/hurd.scm: ..to here. New exported procedure. * gnu/packages/commencement.scm (glibc-final-with-bootstrap-bash) [arguments]: Replace string-match. [inputs]: Same. * gnu/packages/cross-base.scm (cross-libc)[native-inputs]: Same.
