title says 
please
I’m not sure the title really does say everything. Can you spell out the case in a way that might inspire someone to take on the significant effort involved?
I have seen people using fedora as a distro to cross compile easily and quickly, having more toolchains apart from GCC would be interesting, personally I am also interested.
It’s just a consider, I understand the effort involved, that would be the decision of whoever wants to of course
