So you appear to be saying that the cause in the slowdown is the OS and 
not the version of the linker ?  Did you try using the 2.16.91.0.6-5 
version on FC4 ?  If so was it still < 10 seconds for the link ?

Have you tried using any system profiling tools to find out what is 
going on ?  (vmstat, oprofile, etc)

Do have other background processes running on the FC5 machine that you 
do not have running on the FC4 machine ?  Are you using NFS mounts ?

Anyway really if this is an OS issue, you ought to try asking on a 
Fedora list.
