No. They're offsets from the start of that function, as should be
somewhat self-explaining by the way the written: 

	_functionname+0x1234f7

If you don't get filenames and line numbers, chances are your version
of GCC is relatively recent, so the old "symify" doesn't understand
its debug information format any more.  Use bsdsymify instead of
symify, then, as the README for your GCC would have told you to.

Don't worry --- it wouldn't be useful for anything, even if you could.
Dynamic labels are not meant as a substitute for longjmp() or plain
function calls.

RTFM.  Or a C textbook.
