Don't define _FORTIFY_SOURCE on MinGW
Recent MinGW versions require -lssp when using _FORTIFY_SOURCE, which
gdb does (in common-defs.h)
https://github.com/msys2/MINGW-packages/issues/5868#issuecomment-544107564
To avoid all the complications with checking for -lssp and making sure it's
linked statically, just don't define it.

* gdbsupport/common-defs.h: Don't define _FORTIFY_SOURCE on MinGW.
