- added patches athlon and athlon-identify
- athlon causes it to create athlon-* dirs in /usr/lib/rpm, and extends ix86 macro
- athlon-indetify (in %%ifarch athlon) adds capability of identyfing athlon (k7) cpu
  (rpm uses it for choosing dir in /usr/lib/rpm)
- rpm-build needs gcc >= 3.0.3 for athlon
- to build it for athlon, first build for existing arch, install and build it
  with --target=athlon
- release 49
