The fix will be to add .balign to to the SSE4 test near the end of
libcpp/configure.ac, or to avoid using .balign in the SSE4 assembly
code.
I can't explain the results you showed for the libcpp config.log file,
though. Based on those I would have expected to see a failure in
stage 1 as well. Clearly I am missing something.

You try editing libcpp/config.h and change HAVE_SSE4 to 0.
