See the other email thread; you replied (~ 26 hours ago) to my message adding
that "sysdata.rda in 'tools' hanging was wrong". It gets to
the next stage,
which is 'compiler'.

We know by now (thanks to Bryan and Tomas) that src/main/machar.c is the real
culprit due to the long double behaviour on ppc64el.  I presume
'compiler'
calls into platform.c and hence machar.c for calibration or setup.

On the Debian side, I just shipped an updated source package which will skip
long double support on this platform.  That should allow builds to complete,
hopefully, so that we can look into get the build from 'experimental'
into
'unstable' and the distro proper.  In the meantime, there are
alternative
venues for getting R 4.0.0 binaries for Debian and Ubuntu as previously
mentioned.
