So what did I do wrong with this build of 'perf' (other than trying to do it on a Fedora Rawhide box updated to last night? :)
(The obvious hack fix is to change the '#define _BSD_SOURCE 1' in util/util.h
to use _DEFAULT_SOURCE instead, but not sure how that plays on older
userspaces, as that was a glibc 2.19 feature that only escaped about
3 months ago....)
