Build error for simpletest calling arc4random_uniform on Ubuntu 12.04

I get an error on Ubuntu 12.04 building "examples/simpletest".

$ ./configure --enable-simpletest
...
$ make

It looks like Ubuntu has that in a library called 'libbsd'. But even if I make sure that is installed, it isn't linking to the library.

Ah, good catch! I'll fix tomorrow. For now, to make it work, you should be able to build with make LDFLAGS="-lbsd"

My building skills have gotten a bit rusty so I wasn't sure how to get that going... And your fix does work:

$ LDFLAGS="-lbsd" ./configure --enable-simpletest

And then the build went fine, and simpletest runs.

Thanks, Sim
