Turn readline into an internallib for gdb
Can you add the UPADTING entry in here too? This passed an exp run already, correct?
Be sure to highlight reasons for removing it in the commit message - e.g., having ports use readline from ports allows it to be kept up-to-date. Specifically, it's not just because of the GPL that it's being removed.
Here's my take:
20140707: The GNU readline library is now an INTERNALLIB - that is, it is statically linked into consumers (GDB and variants) in the base system, and the shared library is no longer installed. The devel/readline port is available for third party software that requires readline.
