Some great progress! I found the
build-i686-pc-linux-gnu
host-i386-unknown-linux
build directories very suspicous. I found that in my bootstrap I used
the older `i386-unknown-linux' only because I started with a very early
binutils that didn't know about i686-*linux-gnu yet.
So I have changed the entire bootstrap to use i686-unknown-linux-gnu and
configure gcc-4.7.4 using
../build/configure
--build=i686-unknown-linux-gnu
--host=i686-unknown-linux-gnu
--disable-decimal-float
--disable-libatomic
--disable-libcilkrts
--disable-libgomp
--disable-libitm
--disable-libmudflap
--disable-libquadmath
--disable-libsanitizer
--disable-libssp
--disable-libstdcxx-pch
--disable-libvtv
--disable-lto
--disable-lto-plugin
--disable-multilib
--disable-plugin
--disable-shared
--disable-threads
--enable-languages=c
--enable-static

Now, building _muldi3.o from libgcc2.c passes, interestingly indeed the
fresh `xgcc' compiler is used now

no wonder it failed before.
However, now i get this error (I do not have pthreads/pthreads.h).

Thanks a lot for listening!
