Why must the "make.sh" be run as root ?

Hi

I'm trying to do a full build of ipfire, following instructions on :
http://wiki.ipfire.org/en/development/build

I have been able to do a full build (except for build of cdrom failing, 
it seems to be tar complaining that usb/bin/ntpd and other ntp files are 
missing),
but I am wondering why I need to run the make.sh as root.

I can see in the make.sh that a symlink is made for "/tools", so I guess 
one needs root for that.
Is that the only reason ?
Or is the build process putting files on my computer outside the folder 
where I have the source code repo from git ?

Could one use the "fakeroot" command instead, if needed ?

I do not like runing build commands as root, being afraid that something 
is installed / changed somewhere on my development machine.
So it would mean that I need a separate virtual build machine for 
building ipfire.
