These failures indicate that you can't really use -msoft-float to
build applications under AIX, because there is an ABI mismatch between
GCC and the system library if you use that flag. (You'll find
you can't pass float parameters to printf, either.)

Actually, they should be set to UNSUPPORTED or simply not run. They
are not bugs, they are testing functionality that is not supposed to work.
