Description of problem:
The crafty executable dies on SIGILL almost immediately after start.
Steps to Reproduce:
1.just run /usr/lib/crafty/crafty
Possible explanation: the Makefile in the corresponding SRPM forces everything to be compiled with "-march=i686",
even though the binary package is marked as "i386". After rebuilding with "-march=pentium" (which is the CPU I run it on), it
seems to be OK.
Since powertools has been discontinued, the official fix is the package removal.
Since you have found the way to fix it yourself, I'm not attaching a fixed package.
