- autotools dependency tracking isn't generally useful in rpm builds;
disabling it results in cleaner build logs and possibly slight build speedups
- patch from Ville Skyttä
- --target is only ever useful for handful of compiler toolchain packages
and cross-compiler packages are better off setting it themselves if
necessary, rpm messing here only gets in the way
- patch originally from Stepan Kasal
- syncs up with rpm upstream setup
- FFLAGS has a Fedora-specific override forcing us to carry this %configure
copy, need to fix rpm to permit more fine-grained overrides...
- 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

- 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
