gdal (3.4.1+dfsg-1) FTBFS on ppc64el due to ln segfault

[Sebastiaan Couwenberg]

The gdal build is failing on ppc64el due to ln segfaulting, see:

 
https://buildd.debian.org/status/fetch.php?pkg=gdal&arch=ppc64el&ver=3.4.1%2Bdfsg-1&stamp=1641309768&file=log

There are no changes in the gdal (upstream) source since the previous 
upload to experimental that built successfully.

What is causing this breakage on ppc64el?

Kind Regards,

Bas
