This is usually a chicken-and-egg problem: in order to install the
headers, you need to compile libc with the cross compiler; to install the
cross compiler, you need the headers. You can get around this by using the
-Dinhibit_libc hack. It's described at:

  http://www.inkvine.fluff.org/~chris/arm-tools.html#app-inhibit

This page is specifically for a ArmLinux cross compiler, but the basic
idea can be applied to other cross compilers, too. When I use this hack, I
usually build gcc two times:

- compile and install gcc with -Dinhibit_libc hack, and only support C
- compile and install glibc
- recompile gcc without the -Dinhibit_libc hack, but this time with all
  the language support you need
