build failures on ubuntu-latest?

[prusnak]

ISTM that the current master does not build on ubuntu-latest in the github CI

See the following failures of the bitcoin-hwi project:

• https://github.com/bitcoin-core/HWI/actions/runs/9745167713/job/26892446343?pr=742#step:4:386

cc: error: unrecognized command-line option ‘-ftrivial-auto-var-init=zero’

• https://github.com/bitcoin-core/HWI/actions/runs/9745167713/job/26892446696?pr=742#step:4:403

embed/lib/assert.h:43:47: error: ‘__FILE_NAME__’ undeclared (first use in this function)

It would be great if these issues were fixed so the HWI CI works again.
