Remove obsolete gnu libstdc++ from the Android build.

Remove obsolete gnu libstdc++ from the Android build.

For old historical reasons, the GNU libstdc++ headers and libraries
were used in the Android build, in addition to the STLport ones.

This is no longer necessary, so remove them from the build files.

Shouldn't be a problem for WebView (and if it is I'll fix it up after). LGTM.
