Not exactly true, repackaging is still needed for gcc-mingw since the
used paths are different.  The main reason is that extracting the
packages would fail if the directory usr/i686-pc-mingw (and links
inside) is missing, so the postinstall script creates this directory
and links first before the tarball is extracted.
