Unfortunately even restricting it to gcc it still does not work
right. Although I would say that is a bug in gcc:

% gcc -m32 -dumpmachine
x86_64-linux-gnu

-m32 selects 32bit output and that is most certainly no
x86_64-linux-gnu but should be i486-linux-gnu.


I will just have to do this in the source files and use the __ARCH__
defines set by the compiler.
