Re: Bug#772665: produces broken cross compiler packages for mips64el

Waoo, great work.

Now I understand what it is for.

Looong Looong ago, something may make libn32blabla depend on
lib64blabla in control,
so this snap of code exits.

Now we don't have this problem, all libn32blabla depends on

Depends: gcc-4.9-base (= ${gcc:Version}), ${dep:libcbiarch},
${shlibs:Depends}, ${misc:Depends}

No lib64blabla in them, so we should remove these codes.
