platform.machine() on salsa i386 build?

[Ole Streicher <olebole@debian.org>]

Hi,

I have a package (pyraf) where I need to switch off some tests for i386
(but not for other 32-bit platforms). I do this by

import platform
is_i386 = platform.machine() in ('i386', 'i486', 'i586', 'i686')

[...]
@pytest.mark.skipif(is_i386, reason='diff is not identical on i386')
 def test_gki_single_prow():

https://salsa.debian.org/debian-astro-team/pyraf/-/blob/master/debian/patches/Skip-tests-that-are-too-tight-for-i386.patch

However, on Salsa this fails; and it appears that this test is
ignored. Further investigation gave me that there -- during the regular
(pybuild) test -- platform.machine() gives "x86_64", despite of the
32-bit platform.

How can one find out the correct machine here?

Best regards

Ole
