IIRC --dynamic-list forces perf to exports some symbols to
be used by plugins.. don't see this breaking static build

also it's working properly for me:

[jolsa@...va perf]$ make LDFLAGS=-static
...
[jolsa@...va perf]$ ldd ./perf
        not a dynamic executable

unless I miss what you mean by 'really statically-linked' ;-)

Maybe different features enabled/build environment could you
please send the .config-detected along with the build error?

thanks,
