What could be wrong with cross compiling Qt 4.8 under Linux for Windows?

Question

linux

I tried to compile for Windows 32 following these tips,
but I got this error:
CROSS_COMPILE=i686-w64-mingw32-: unknown argument
When I try to compile without the above macro, notifications appear for undefined references to various codecs:

With what it can be connected? And how can this problem be solved?
