I'd welcome it.
However it would be a very challenging task on all levels:
- Fedora's rpm and some components the build-infrastructure have serious
issues related to cross-building.
- A cross compiler alone is not worth it, you need a whole zoo of
further cross-target packages to make it usable.
I don't see why. If you assume that someone compiling for user space
has a vague idea what they are doing, they will know how to install the
-devel packages for their target system somewhere the compiler can find
them. The x-compiler package itself wouldn't need much more than the
target's libc. I don't think we need to cater for people who can't
even figure out how to unpack what they need for the target system.
David is, I think, concerned about kernel building, so he doesn't even
