> I don't know how you manage it, but I can tell you it is not reasonable to expect people to compile every compiler they want to use on every system they want to use it.

If you're dealing with bare metal projects (kernel programming or micro controllers), building binutils and gcc for cross compiling from source is pretty much required. There are scripts that help and some distros have cross compilers in their package managers.

But building GCC is not difficult and it pretty much works first time, every time.
