For cross gcc I guess the important question is, do we want gcc-4*.src.rpm to build all the cross compilers (and, is C enough, or do we need C++ too?), or do we have one cross-gcc-4*.src.rpm that semi-loosely tracks gcc-4*.src.rpm and builds all the cross compilers (BuildRequires all the cross-binutils and all cross-glibc/kernel-headers), or each cross would have its own src.rpm? I think the last one would be a maitanance nightmare. I hope cross Fortran and especially cross Java (or cross Ada/ObjC/ObjC++) aren't needed, especially libjava builds for eons and has myriads of target dependencies.
