[PATCH] build.sh: new command line option

[Mariusz Ceier]

New command line option for autoresuming build:
./build.sh --clone -rf build.modules prefix

When build.modules doesn't exist it is equivalent to:
./build.sh --clone -f build.modules prefix

When build.modules does exist it is equivalent to:
./build.sh --clone -f build.modules -r `tail -n 1 build.modules` prefix
