The build of jpeg-xl against new libhighway (1.2.0-3ubuntu4) is failing
because of a failing test:
...

This issue has been reported by @schopin to highway upstream and fixed for
highway at the version 1.2.0-3ubuntu4 by forcing the use of gcc-14.
The root cause is not yet well understood and this can only be considered as a
work-around for now.
To fix jpeg-xl, there are 2 work-arounds:
- force the baseline to power8 instead of power9 (using cflag : -cpu=power8)
this is confirmed to fix the issue with the upload to the PPA:
https://launchpad.net/~hectorcao/+archive/ubuntu/lp2121375-jpeg-xl-baseline
- forcing the use of GCC-14
this is confirmed to fix the issue with the upload to the PPA:
https://launchpad.net/~hectorcao/+archive/ubuntu/lp2121375-jpeg-xl-gcc14
I propose to go with the latter that would be the less worse solution and it is
similar to the work-around done for lib highway.
