That's a typo that *every* other arch has because they copied the code
from i386, I think rth was the only one anal enough to fix the spelling
mistake ;)

I snatched the C99 spec and fixed our implementation based on my reading
of the current code, other arch code, and the spec. The correct
feupdateenv is provided below.

I'm sending this upstream to debian, so we can build again.
