This sounds more like bootstrapping a system (a la Linux-from-scratch)
than cross-compiling.
TBH, I don't know too much about this, but I could imagine that one usually
needs to point LD_LIBRARY_PATH to the newer glibc at some point, right?

Back to the patch - does the attached work for you?

Have a nice day,
