8As part of the menuconfig development, I encountered some outdated information in the cross-build instructions, libc/EGLIBC.cross-building. This patch updates the file with new (and tested) instructions. It is unrelated to the menuconfig support, but applies after.
9
10My testing was done with an ARM target, and an x86_64 Linux host, so I converted the instructions to use those host/target types from the original i686/powerpc. Hope that's ok.
