[Discuss-gnuradio] Note on commit 9531

[Tom Rondeau]

Just a head's up with my recent merge into the trunk. Because it removes 
a few unnecessary and unused blocks in lib/general, if you don't clean 
up the dependencies in this directory, future makes will fail. The 
easiest way to do this is probably just do a "make distclean" in that 
directory. Then rerun bootstrap, configure, and make.
