Bug#908481: mozjs60: FTBFS on armel: test262/built-ins/TypedArray/prototype/fill/fill-values-conversion-operations-consistent-nan.js: Test262Error: NaN value #2 (Testing with Float32Array.)

In mozjs60 (Spidermonkey 60, the standalone version of the Mozilla
JavaScript interpreter corresponding to Firefox 60.x ESR), the test
test262/built-ins/TypedArray/prototype/fill/fill-values-conversion-operations-consistent-nan.js
fails on armel.

The point of this test appears to be to check that a FloatArray filled
with a particular encoding of NaN (Not-a-Number) using fill() has the same
binary representation as a FloatArray that was explicitly initialized.
This works for 0/0 and for Infinity/Infinity, but for some reason not
for -(0/0).

If this can't be fixed soon, we should skip this test or ignore the test
failure and downgrade it to non-RC.
