is that "install glibc headers" step in crosstool necessary?

and it's quite trivial to patch all the other arches (except for ia64) to not 
need libc or kernel headers

the stuff ive found have always talked about mismatch exception handling 
between libgcc_s and the libc ...

so what if we do:
- binutils
- bootstrap C (no libc headers)
- kernel headers
- libc
- 'normal' C (and optional C++/whatever addons)

will the final toolchain be OK ?
