- as per https://fedoraproject.org/wiki/Features/XZRpmPayloads
- lowish compression preset level to keep deltarpm rebuild time tolerable
- source rpms dont really benefit from XZ compression as the contents are
typically tarballs which are already compressed
- patch from Bill Nottingham
- remove any existing buildroot contents and safely create a new one
- patch originally from OpenSUSE / Michael Schroeder, adopted to Fedora
by Tom "spot" Callaway

- update config.{guess,sub} to 2003-06-17
- define VENDOR to be redhat only when /etc/redhat-release present
[suggested by jbj]
- put VENDOR in vendor field in our config.guess file for
ia64, ppc, ppc64, s390, s390x, x86_64 and elf32-i386 Linux
- drop the --host, --build, --target and --program-prefix configure options
from %%configure, since this causes far too many problems
