Subject: perf symbols: debuglink should take symfs option into account
X-Git-Tag: omap-for-v4.2/o2_dc~146^2~66^2~57

perf symbols: debuglink should take symfs option into account

Currently code that tries to read corresponding debug symbol file from
.gnu_debuglink section (DSO_BINARY_TYPE__DEBUGLINK) does not take in
account symfs option, so filename__read_debuglink function cannot open
ELF file, if symfs option is used.

Fix is to add proper handling of symfs as it is done in other places:
use __symbol__join_symfs function to get real file name of target ELF
file.
