Nicolas, Stroller (and the man page) is right...
As "system" is part of "world", an "emerge -e world" would recompile
every single package, along with all dependencies, a full system
recompile, if you, for instance, change your CFLAGs to a generic one
before it, at the end your system would be prepared to be used with a
different processor.
