Subject: tests: Expect some floating-point tests to fail on i386
Upstream assumes everything uses SSE mathematics, but SSE isn't in
Debian's baseline for i386, so we are stuck with i387 and its weird
80-bit floating point registers. We can't even work around this with
-fexcess-precision=standard, because mozjs is C++.
