--- Comment #8 from Michael Matz <matz at suse dot de> ---
This breaks at least the perf build from linux kernel 5.7 as nm is used to
construct a symbol list for feeding into ld, which now contains '@' characters
which aren't liked by ld (of course).  See e.g.

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1887397

Is it really a good idea to change the output format of basic tools that might
be
used in machine processing context?  (And I note there doesn't seem to be an
cmdline option to get the old behaviour back, so fixing the problem now entails
further massaging of nm output to cut off /@.*/ )
