Bad performance on alpha? (make buildworld)

[Petri Helenius]

Talking about different instruction sets and compiler scheluding 
options. Would it be considered a good idea to introduce a sysctl which 
would contain the maximum mcpu= value for the currently running 
architechture? This way one could provide with multiple executables and 
a startup script, in the fashion of:
prog.i386
prog.pentium2
prog.pentium3
prog.pentium4
prog.athlon-mp
etc...

This would ease utilization of various options and probably excersize 
the CPUs to better extent.
