Arnaldo Carvalho de Melo 1286e959a5 perf symbols: Robustify reading of build-id from sysfs 
[ Upstream commit 7934c98a6e ]

Markus reported that perf segfaults when reading /sys/kernel/notes from
a kernel linked with GNU gold, due to what looks like a gold bug, so do
some bounds checking to avoid crashing in that case.
