Not a major problem, but would be good if we were robust in this area:

    LINK /tmp/build/perf/perf
/usr/bin/ld: /tmp/build/perf/ui/gtk/browser.o: relocation R_X86_64_32
against `.rodata.str1.1' can not be used when making a shared object;
recompile with -fPIC
/tmp/build/perf/ui/gtk/browser.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
make: *** [/tmp/build/perf/libperf-gtk.so] Error 1
make: *** Waiting for unfinished jobs....
make: Leaving directory `/home/git/linux/tools/perf'
[acme@zoo linux]$ 

This happened because I was retesting the whole series after noticing I
was testing as root, that has a symlink of ~acme/bin/perf to
~root/bin/perf but was lacking a symlink of ~acme/lib64/ to
~root/lib64/, so that as root perf could find the libperf-gtk.so file.

So I just rolled back the 3 patches in this series to rebuild and
retried, but when I reapplied the first patch in this series I got the
above error, i.e. the make process got confused and didn't properly
rebuilt a file in the expected format for linking, after forcefully
removing my build dir and rebuilding everything it got back to working.

But I expected that after the first patch 'perf --gtk' would work, and
it doesn't.

Now even after I applied the whole series I don't get --gtk to work,
neither as a non-root nor as root :-\

Investigating...
