It doesn't get to run it.  The problem shows up while compiling the
object file that would be added to the library with ar.  Most likely,
GCC is using the wrong assembler.  Run 

/home/axk/cross/mingw-bld/gcc/xgcc -B/home/axk/cross/mingw-bld/gcc/ \
-B/home/axk/mingw/i386-mingw32/bin/ \
-I/home/axk/mingw/i386-mingw32/include -O2 \
-I../../src/gcc/gcc/../winsup/include -DCROSS_COMPILE -DIN_GCC \
-I./include   -g1  -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED   -I. \
-I../../src/gcc/gcc -I../../src/gcc/gcc/config \
-I../../src/gcc/gcc/../include -c -DL_muldi3 \
        ../../src/gcc/gcc/libgcc2.c -o _muldi3.o -v

and see which assembler it runs.  The FAQ has some suggestion on how
to arrange for GCC to run the appropriate assembler.
