math-emu on buildd machine?

[Paolo Bonzini <paolo.bonzini@lu.unisi.ch>]

Is the math-emu module loaded (or compiled in the kernel) on the buildd 
alpha machines?  The gnu-smalltalk package is failing for 3.0 because 
the emulator converts erroneously a denormal float to double:

st> p:= (FloatE coerce: 1) timesTwoPower: -149.
2.6524948e-315

(2^-149 is actually ~1e-44) despite the program is compiled with -mieee.

If it is, it is a bug in the emulator and the best solution is to XFAIL 
the test on alpha.  But if it is not loaded, maybe it should...
