  This fixes the test failures on our machines.
Thanks for the feedback.

This bug indicated a flaw in our testing, since the bulldozer mpn_mul_1
was completely non-functional under the 64-bit Windoze ABI.

We now test all x86 and x86-64 code from a fat build on the Windoze
machine as well as a ELF ABI system.  The results are
reported as *-fake (it is based on providing a 'fake' cpuid overriding
the real cpuid).
