So, I've stumbled on this on debian:experimental:
LINK /tmp/build/perf/perf
/usr/bin/ld:/tmp/build/perf/libtraceevent-dynamic-list:2: ignoring invalid character `@' in script
/usr/bin/ld:/tmp/build/perf/libtraceevent-dynamic-list:2: ignoring invalid character `@' in script
/usr/bin/ld:/tmp/build/perf/libtraceevent-dynamic-list:2: syntax error in dynamic list
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile.perf:637: /tmp/build/perf/perf] Error 1
I'll tentatively add this patch to see if it then passes all the tests
everywhere...
