Warner Losh 65b8a300df Revert r326855: Cargo cut a fix for the regressions r326585 caused.
This was an experiment that landed in the wrong branch and was pushed
accidentally. It's best if it is ignored because the difference was
due to vers.o being different, not float.o... And it was confirmed to
not fix anything...
