[R-pkg-team] Bug#983749: The autopkgtest test depends are not available on s390x

[Sebastien Bacher]

Package: r-cran-sf
Version: 0.9-7+dfsg-2

debian/tests/control has a Depends on r-cran-lwgeom which isn't build on
s390x anymore since
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=961211 , it makes the
s390x autopkgtests fail
(Debian has currently no builder set, but log from Ubuntu
https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-hirsute/hirsute/s390x/r/r-cran-sf/20210228_211230_bcd0f@/log.gz)

Either the depends should be removed or the package should also not be
built on s390x anymore?
(r-cran-stars is in a similar situation)

Cheers,
