[Buildroot] [PATCH 1/1] package/tmux: fix BR2_SHARED_STATIC_LIBS

[Fabrice Fontaine]

tmux uses custom --enable-static option, instead of standard libtool
directive resulting in the following build failure with systemd or
utf8proc raised since commits
1f618aa388535181c281c85e2b5264532de4ef0f and
e279599d255a79c08ef20b97b96eb248689d52a9:

checking for utf8proc.h... yes
checking for library containing utf8proc_charwidth... no
configure: error: "utf8proc not found"

In file included from tmux.h:34,
                 from alerts.c:23:
compat.h:379:18: error: conflicting types for 'forkpty'; have 'pid_t(int *, char *, struct termios *, struct winsize *)' {aka 'int(int *, char *, struct termios *, struct winsize *)'}
  379 | pid_t            forkpty(int *, char *, struct termios *, struct winsize *);
      |                  ^~~~~~~
