Cool, but I think you only need to set one variable. The system should
be able to figure out the rest it self.
I mean, the setting over is meaningless since it will use a 64bit
compiler with a sysroot that contains 32bit libraries.

Then the distributions are wrong. You only need that mingw symlink
when building the cross compiler, not for using it.
The i686-w64-mingw32 (and x86_64-w64-mingw32) are very standard when
using i686-w64-mingw32 or x86_64-w64-mingw32 as a target for binutils
and gcc.
Note that they are only standard for mingw-w64, they are not standard
for building other targets.
