m4: fix build for mingw32 host
While building a canadian toolchain for windows host (any target),
the build failed for m4 host companion_tool with a recent mingw-w64
(at least 7.0.0).
m4 needs stack smashing protection which is not part of mingw-w64 c
library and an explicit trigger to link w/ libssp is needed.
