[Cin] blds/bld_prepare.sh update

[Andrea paz]

I tried to change the manual by recommending to build as a normal
user. See if you think it is okay. Particularly the part about the
CinGG desktop icon. Can it also be done without being sudo?

PS: (@Miroslav) I am interested in your steps to build in Debian
(given my inadequate knowledge in compiling); can you explain them to
me?
