[Bug-apl] undefined reference to dlclose

[Jay Foad]

When I try to build on Ubuntu 13.10, I get:

apl-NativeFunction.o: In function `NativeFunction::~NativeFunction()':
/home/jay/svn/gnuapl/trunk/src/NativeFunction.cc:84: undefined
reference to `dlclose'

... followed by a load more undefined references to dlsym, dlopen etc.
This patch fixes it for me:

 # enable readline support if libreadline is present and the user

Note that this is in addition to the problems with linking against
libreadline, which Elias reported in another thread.

Thanks,
Jay.
