[PATCH modular 01/13] build.sh: expose the PREFIX variable for the user to set

[Gaetan Nadon]

Currently PREFIX is an internal build.sh variable which is used
to emit the --prefix option to all modules.

Make this variable part of the public interface and pick-up the value
from the environment.

That variable is refered to in 6 places in --help but user cannot set it.
