libtraceevent: Fix build with binutils 2.35

39efdd94 · Ben Hutchings <[email protected]> · 2020-07-25 02:06:23 +01:00

In binutils 2.35, 'nm -D' changed to show symbol versions along with
symbol names, with the usual @@ separator.  When generating
libtraceevent-dynamic-list we need just the names, so strip off the
version suffix if present.
