That's why I suggested a small sh script to source, to setup that environment.
Personally, I do an awful lot more than that just to build a native chroot,
let alone cross-compile. And I really don't see the hardship for these brave
"cross-compilers" of yours in sourcing a small setup script, which can be
added to ~/.bashrc or even the system-wide one, for anyone who really wants
it to apply whenever they login. Is this somehow beyond our most advanced
userbase?

People may install crossdev to get a cross-compile environment, but it's a
broken design if it's not contained. And BS about how you think it should
ALWAYS go for everybody, only leads to borked "solutions" elsewhere like
telling the people on an amd64 install that they have to run some god-awful
"new" %multilib thing to compile for their secondary ABI. That's just as
counter-intuitive, when you could just fix your borkage and have a clean
setup for everyone.
