This is the single package which won't build with make V=1. Now that
RPM has %_make_verbose to override this, use it instead of redefinining
%make_build.
Previous to F33, the files /usr/lib/rpm/config.{guess,sub} existed, and
this package copied them into the autoconf directory. This was added in
2008 with no explanatory comment other than "new upstream version". RPM
no longer includes those files, though copies do still exist in
/usr/lib/rpm/redhat. The package appears fine without them.
