waf:lib/replace: fix a build error with non-gcc compilers

3a175830e579ab10231439657b23733338cd5634 added that variable which should have
been an empty initialization here. -Wno-format-zero-length (which might be
unsupported by the compiler) should not be set if we really only want to
initialize the cflags.
