Oddly the rust.log doesn't contain the FAILed tests.

Luckily the upload does contain the bunsen link:
https://builder.sourceware.org/testrun/4089d04b3ec71f873716bdac207b31ec43a1e00e

Which contain the full rust.log file (under filelist):

This is odd. The -fno-fat-lto-objects variant is the only failure. But
other builds with -fno-fat-lto-objects PASS:
https://builder.sourceware.org/testrun/4089d04b3ec71f873716bdac207b31ec43a1e00e?dgexpfile=rust%2Fexecute%2Ftorture%2Fexecute.exp

Also all other arches/distros passed (except s390x of course):
https://builder.sourceware.org/buildbot/#/changes/3381

The rawhide builder should not really be slower than other
builders. So I am not sure why it timed out but others didn't.

Cheers,
