[strongSwan] Where to specify -no-undefined?

[Derek Cameron]

I am building strongSwan natively on Windows with MSYS2 and MinGW-w64 following the instructions at https://wiki.strongswan.org/projects/strongswan/wiki/Windows.

The make terminates with messages:

Where and how do I specify -no-undefined?
