Did you already get the glibc, or did the problems appear before? Maybe it 
would be enough to just replace the glibc with one that contains the 64 bit 
headers.

I tried to compile glibc independently with
   CFLAGS="-march=mips64 -mabi=64 -O2"
just to obtain the header file, but it fails with

Unless you have the glibc at hand, I would drop the issue for the moment 
and wait for Ludovic to finish implementing the cross compiling approach.
