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

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
