Improving the crossStripping. A cross-glibc gets broken if stripped by the

native strip. So we now distinguish dontStrip and dontCrossStrip. I updated
the expressions for glibc-2.9 and glibc-2.11 accordingly.
I could get rid of the cross-glibc depending on the cross-gcc-stage-static.

Enabling nls in the final cross-gcc.

I still have problems on wint_t/wchar_t not working on cross build. Gettext
does not build.
