Of course. In that case, it would be much better, to be able to *disable*
the implicit extern "C" feature for X86 and ARM and whatever architecture,
just because I certainly know it when I call configure.

To my surprise a cross compiler for --target=arm-eabi has a completely
different syntax in the system headers than one for --target=i686-pc-linux-gnu.

In my eyes, configuring that somewhere in gcc/config is awkward in that
use case. Do you see my point?
