Hi,
While building today's Fedora rawhide kernel, there was a failure
building perf with -j4 [1]:

The gcc call to compile plugin_scsi.o seems to be invoked twice which would
account for the ld failing. Unfortunately, this failure seems to be
intermittent and I've only been able to reproduce it once outside of
the Fedora build environment so bisection doesn't seem feasible.
The build invocation for this was changed in
0c3b7e42616f ("tools build: Add support for host programs format") so
I'm suspicious of that commit. I'm reverting that commit for today's
build but I'm not sure how much that's going to indicate given the
intermittent nature of the failure.
Any ideas?
Thanks,
Laura
