--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> --- As I mentioned before, target libraries are multi-lib'ed. But libgccjit is NOT a target library, it is a host library. The only way for the host library to be multi-lib (arch'ed) is building GCC twice. Because GCC itself is only built for the host rather than built for the target too.
