pentium4 kernel

[Dennis Gilmore <dennis dgilmore net>]

Hi,  quite probably this is a stupid question  i installed the kernel src rpm  
and configured a spec file for pentium4 and built the kernel packages  with 
rpmbuild -ba --target pentium4 kernel.spec  rpm  tells me the resulting rpms 
are uninstallable im wanting to rebuild glibc for pentium4 also as a test to 
see how performance goes  mostly with multimedia applications.  how hard 
would it be to implement in rpm  to allow package built for pentium4 in a way 
similiar to the athlon's

Regards

Dennis
