perf annotate: Automatically pick up vmlinux in the local directory
Right now kernel debug info does not get resolved by default, because
we dont know where to look for the vmlinux.
The -k option can be used for that - but if no option is given, pick
up vmlinux files in the current directory - in case a kernel hacker
runs profiling from the source directory that the kernel was built in.
The real solution would be to embedd the location (and perhaps the
date/timestamp) of the vmlinux file in /proc/kallsyms, so that
tools can pick it up automatically.
