perf symbols: Robustify reading of build-id from sysfs
[ Upstream commit 7934c98a6e04028eb34c1293bfb5a6b0ab630b66 ]
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.
