I'm following the guide below to build a mingw-w64 tool chain to cross compile for windows64 on Fedora 26. (I can't use the buildin tool chain, as the Fedora people decided to activate certain compiler options that i want disabled.)

I know it is not the most recent one, but all steps seem reasonable and version independent.
So now here is my problem: When I try to do the last gcc build "Gcc, pass 2", I am presented with the following error message:
<path to build dir>/mingw-w64/build/gcc/./gcc/xgcc -B<path to build dir>/mingw-w64/build/gcc/./gcc/ -L<path to local install dir>/mingw-local/x86_64-w64-mingw32/lib -L<path to local install dir>/mingw-local/mingw/lib -isystem <path to local install dir>/mingw-local/x86_64-w64-mingw32/include -isystem <path to local install dir>/mingw-local/mingw/include -B<path to local install dir>/mingw-local/x86_64-w64-mingw32/bin/ -B<path to local install dir>/mingw-local/x86_64-w64-mingw32/lib/ -isystem <path to local install dir>/mingw-local/x86_64-w64-mingw32/include -isystem <path to local install dir>/mingw-local/x86_64-w64-mingw32/sys-include -g -O2 -m32 -O2 -I../../../../../gcc-7.2.0/libgcc/../winsup/w32api/include -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector -Dinhibit_libc -I. -I. -I../../.././gcc -I../../../../../gcc-7.2.0/libgcc -I../../../../../gcc-7.2.0/libgcc/. -I../../../../../gcc-7.2.0/libgcc/../gcc -I../../../../../gcc-7.2.0/libgcc/../include -DHAVE_CC_TLS -DUSE_EMUTLS -o _muldi3.o -MT _muldi3.o -MD -MP -MF _muldi3.dep -DL_muldi3 -c ../../../../../gcc-7.2.0/libgcc/libgcc2.c

I'm using following version numbers:
- binutils-2.29
- gcc-7.2.0
- gmp-6.1.2
- mingw-w64-v5.0.3
- mpc-1.1.0
- mpfr-4.0.0
Also Fedora's own gcc is version 7.2.1, which i can't download from gnu.org. (I mention it anyway since some solutions I found mentioned there might be a version conflict.)
I'm stuck here, hope anyone can help.
