Oh, one stap back ... make will start this command in the folder util:

make[2]: Betrete Verzeichnis '/home/mario/libs/win32/gtk+-3.13.5/util'
gcc   -mms-bitfields -I/home/mario/build32/include/glib-2.0
-I/home/mario/build32/lib/glib-2.0/include   -g -O2 extract-strings.c
 -L/home/mario/build32/lib -lgobject-2.0 -lgmodule-2.0 -lglib-2.0
-lintl    -o extract-strings.exe

I think thats wrong that he would build a linux binary with the cross
compiled libs. If i lat them ignore this folger, later it says:

/bin/bash: Zeile 1: ../util/extract-strings: Datei oder Verzeichnis
nicht gefunden (file or folder not found)

So i think its a bug that he will cross compile a util like all other,
use the gnu-linux compiler und will use the result later for processing.
