[PATCH 0/1] MR1833: libs/wine: Only define exe_link when needed

[Gerald Pfeifer (＠gerald)]

Revision 24b26f8bd6a49c855eec417a6585d44c9458e3ec changed FreeBSD
(and DragonFly) not to use /proc any longer. Hence we also do not
need the exe_link variable on those two platforms, either. Avoid
declaring it there.

(This avoids a compiler warning about an unused variable with GCC 12.)
