# unreproducible builds.  Similarly, GNUMAKE is deliberately set to
# make: as of make-dfsg/4.3-1 the make package provides a
# /usr/bin/gmake symlink, but as of December 2021 it is missing on
# GNU/Hurd and GNU/kFreeBSD since they provide only older versions of
# make-dfsg.  Since gnustep-config is in the arch:all package it is
# set to "gmake" which then gives empty output when invoked on
# architectures lacking the symlink.
