on my amd64 sempron 1.6GHz with 512 Megs, the concatenated versions takes more
then 3 hours. Because it uses all available RAM and a huge ammount of swap
space. The normal file by file compile takes only 1 hour.
My harddrive is not the slowest, so it's more an issue of used memory.

Well, for Ubuntu I added the -i switch to avoid concatenating source files,
because I think there will be issues, with systems compiling source packages
with less then 512 Megs of physical memory and 1gb of swap space.
think about the 256 megs of physical memory and 512 megs of swap space. I was
using here actually between 750 to 800 megs of memory (physical + virtual).
