sysutils/openipmi: update 2.0.25_1 to 2.0.26
Makefile silent portlint; reorder GNU_CONFIGURE and INSTALL_TARGET; readline.so (devel/readline) is now part of LIB_DEPENDS; USES got readline added to the list; sorted. post-patch 13.10. Verbose Build Logs; reinplaced editline/readline.h (served by base's libedit). files/patch-unix_selector.c we do not provide EPOLL_PWAIT, so fdc->saved_events = 0 is never used.
