Shaun Jackman 73260c145f readline: fix test
The current test output is correct for libedit but not for readline.
Without specifying the library search path, this test was in fact
linking against /usr/lib/libreadline.dylib, which is simply a symlink
to libedit.3.dylib

Closes #706.

OS X provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

# The 6.3 release notes say:
# When creating shared libraries on Mac OS X, the pathname written into the

# Software will link against libreadline.6.dylib instead of libreadline.6.3.dylib.
# Therefore we create symlinks to avoid bumping the revisions on dependents.
