[rock-user] Fix build scripts on Ubuntu

Hi all,

here's the solution to a problem I had when using Ubuntu as a build host.

In Ubuntu 6.10, bash does not properly execute some ROCK Linux build 
scripts; ./scripts/Build-Pkg will abort with several segmentation faults when 
run with this bash binary. From what I've heard Kubuntu 6.10 and 7.04 have 
the same problem. To fix this, download, build and install bash from source; 
these instructions assume your ROCK Linux source tree is located 
at /usr/src/linux:

	cd /usr/src/rock-linux
	sudo bash

	./scripts/Download bash3
	tar xf download/mirror/b/bash-3.2.tar.bz2
	cd bash-3.2
	for x in ../package/base/bash/bash3/*.patch ; do patch -p1 < $x ; done
	./configure --without-bash-malloc
	make

	mv /bin/bash{,-orig}
	cp -a bash /bin/bash

	exit
	sudo bash

Now you can use the ROCK Linux build scripts without errors. 

With best regards,
Stefan Fiedler

P.S: Sorry for the cross-post.
