Subject: [PATCH] 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.
