Hi,=20

with master on my laptop the following tests fail when building the 32bit a=
bi for x86-64:
=46AIL: math/test-double-j0
=46AIL: math/test-float-ctan
=46AIL: math/test-float-j1
=46AIL: math/test-float-y0
=46AIL: math/test-float-y1
=46AIL: math/test-float32-ctan
=46AIL: math/test-float32-j1
=46AIL: math/test-float32-y0
=46AIL: math/test-float32-y1
=46AIL: math/test-float32x-j0
=46AIL: math/test-float64-j0

The normal 64bit abi passes fine.
