IBM libm integration done

[Ulrich Drepper]

I've finished the IBM libm integration.  I get again no errors in the
test suite (and obviously no link problems either).  I've not yet
adjusted the error values.  Oh, and this is all on Alpha.  Your
mileage may (but shouldn't) vary.

For those interested, the only problems I found were namespace issues
and the handling of boundary cases.  Fixing the latter took me the
whole afternoon.
