# grep is the only package in this list that INSPECTS the version of the m4
# macros its build host provides, and refuses to proceed on the serial Ubuntu
# ships. It is not detecting a real incompatibility on s390x -- the same
# refusal happens on any Ubuntu host, x86 included.
#
# The release tarball is already bootstrapped: configure, Makefile.in and the
# gnulib tree are present. Re-running ./bootstrap regenerates what is already
# there, so skipping it costs nothing.
