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
# library (install_name) no longer includes the minor version number.
# Software will link against libreadline.6.dylib instead of libreadline.6.3.dylib.
# Therefore we create symlinks to avoid bumping the revisions on dependents.
# This should be removed at 6.4.
