Fixing the gcc-wrapper, so it does not link when gcc is called with '-x

something'.
It should not link at least for '-x c-header' and '-x c++-header', and maybe
link for '-x c' or '-x c++', but we expect noone will be linking using these
later strings.

Adding opencv, which required '-x c-header' working, and that's why I have
updated gcc wrapper.
