David Carrillo-Cisneros 6467753d61 tools lib traceevent: Robustify do_generate_dynamic_list_file ... The dynamic-list-file used to export dynamic symbols introduced in commit e3d09ec812 ("tools lib traceevent: Export dynamic symbols used by traceevent plugins") is generated without any sort of error checking. I experienced problems due to an old version of nm (v 0.158) that outputs in a format distinct from the assumed by the script. Robustify the built of dynamic symbol list by enforcing that the second column of $(NM) -u <files> is either "U" (Undefined), "W" or "w" (undefined weak), which are the possible outputs from non-ancient $(NM) versions. Print an error if format is unexpected. v2: Accept "W" and "w" symbol options.
