test failure on ppc64el architecture

[mr-c]

Hello, in Debian we are getting an interesting test failure when running the TCGAbiolinks version 2.32.0 on a ppc64el architecture system.

This isn't a new failure, we've seen it since at least version 2.16.0, but we need to decide to either skip it or fix it.

Thanks for looking into this and please let us know if you have an idea for a fix, or if you suggest skipping that test on ppc64el.

a Dockerfile to reproduce, I named it r-bioc-tcgabiolinks.Dockerfile

Change to an empty directory and run podman build -f ../r-bioc-tcgabiolinks.Dockerfile --platform linux/ppc64le .

Of course docker build … also works.
