No. It wouldn=E2=80=99t for a number of reasons. First, you can often = mix hard-float and soft-float libraries with no ill effect tot he upgrade process (though not always). Second, I=E2=80=99ve implemented code in the run time linker to link in the correct hard vs soft libraries. = Third, I=E2=80=99ve implemented a libsoft that=E2=80=99s like lib32 so you can = run both types of binaries on the same system, if you need to for some reason. In fact, its so that the upgrade process results in better behavior that I=E2=80=99ve gone down this path. I have a few loose ends still to = tidy up on this, but haven=E2=80=99t had the time to push it through to completion.
