I don't do that for my own builds, but the official builds do add this flag
somewhere.

gcc does not enable this flag by default either. If Wine is built with default
configure options (no messing with flags at all), it was already ok. The flag
is added explicitly in official builds.

E. g.,
https://dl.winehq.org/wine-builds/fedora/30/x86_64/wine-devel64-4.21-1.1.x86_64.rpm:


rpm -q --queryformat="%{NAME}: %{OPTFLAGS}\n"
./wine-devel64-4.21-1.1.x86_64.rpm:

-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2
-Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong
-grecord-gcc-switches  -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64
-mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection
-fcf-protection
