This doesn't reproduce for me. I did the following, and it worked
fine.

make distclean
./configure --arch=arm --cross-prefix=arm-linux-gnu-
make
./configure --arch=arm64 --cross-prefix=aarch64-linux-gnu-
make clean && make


But anyway I would suggest you do your 'make clean' or even a
'make distclean' *before* running configure the second time.
Otherwise you'll leave old object files around from the previously
configured arch. I.e. you want 'make clean' to apply to the
currently built config, not the new (not yet built) config.
