Allow probing on kernel modules when 'perf' is built without debuginfo
support.
Currently perf-probe --module requires linking with libdw, but this
doesn't make sense.
E.g.
----
# make NO_DWARF=1
# ./perf probe -m pcspkr pcspkr_event%return
Error: unknown switch `m'
----
With this patch
----
# ./perf probe -m pcspkr pcspkr_event%return
Added new event:
probe:pcspkr_event (on pcspkr_event%return in pcspkr)
You can now use it in all perf tools, such as:
perf record -e probe:pcspkr_event -aR sleep 1
