are replaced with .include "../../devel/readline/buildlink3.mk", and
USE_GNU_READLINE are removed,
* .include "../../devel/readline/buildlink3.mk" without USE_GNU_READLINE
are replaced with .include "../../mk/readline.buildlink3.mk".

Problem 1: It's broken, it can't link to libmysql
Problem 2: If it could, it would affect PLIST
So disable MySQL detection for now, sqlite3 is what's used.
I suspect there are other CMake detection logic that aren't accounted
for yet in Konoha.
