I think the point is that if you are dealing with building a complete
distro, or a large set of packages, then the $PREFIX variable only has
to be set in one place, and then changed only in one place to rebuild
the same set of packages for another arch with a different --prefix=

Sure, the porting process is far more involved but then when it comes
to time automate the procedure then I could imagine this global $PREFIX
value could be very useful and far better than using sed to mass change
any --prefix value in individual PKGBUILDs.

I could also using this value to set the -DCMAKE_INSTALL_PREFIX value
for KDE4s cmake invocation too.
